[Q] Time to scrap lagfixes? (JPA/JPO)

Has the time come to finally scrap all the lagfixes with the release of JPA/JPO?
Please, no Quadrant or similar synthetic arguments against. The "real-feel" of the phone is the only relevant benchmark.
So, in your experience in the operation of the new firmwares, comparing them in a native vs. lagfixed state, is it time to dispense with the lagfixes?

Don't think so....
But JPO is speedy when fresh.
Lag is still there, less noticable, but there, you can feel it especially during parallel download and installing apps or when you have a running background updating/sync process.
Voodoo is mature enough anyway, infact, I kinda do miss Voodoo's brightness and color fix on 2.2.

I'm on Jpa,don't feel the NEEd for lagfix...i gets' hung for a while on installation and other small slowdowns,but it's really good overall (noticeably better than cooked jpm/jp6,at least)

Nope, no reason to dump them yet...
Media scanning still takes a while in stock, while with a lagfix it's about 2 seconds. So the phone is in a fully usable state much sooner after booting or when adding/deleting media on the phone.
I also used DolphonHD browser as a test.
On a fresh boot on stock firmware, it takes about 6 seconds to start up.
With a lagfix (I used Advanced EXT4 with one of those custom kernels) it starts up within 2 seconds on fresh boot.
Samsung needs to dump this RFS crap, it's a horrible joke.

There is definitely still lag and random pauses in JPO, no question about that. Although it may be a slight improvement over previous Froyo betas, you still need an EXT4 lag-fix to eliminate the lag and pauses that exist in stock JPO.

No - user experience (especially with RSS reader) is still much better with OCLF (10 times faster).
Maybe, if I didn't use RSS reader which requires fast IO I'd live without OCLF...

Oops! I voted no, but wanted to vote yes!
I use JPO and I experienced lag without apps installed.. So clean it lagged. I didn't clear the sdcard before the lag (I think it's useless), but I did reset to factory defaults.

Just like all the Eclair releases, Froyo certainly seems to be getting better with every "release". As already mentioned a few posts earlier, JPA certainly zooms when fresh.
That said, it really is too soon to get rid of lagfixes. When Froyo matures to the level of, say JM9, then would be an appropriate time for such a thought. Till then, hello Voodoo....

The best test of lag would be NewsRob imo. Can someone with a non lagfixed JPO test it out? I can already confirm it flies on JPO + Voodoo.

I dont have any real lagging issues on my phone but I can see that moving around the inbox is definitly faster with a lagfix, the rest of the phone operations are pretty smooth woth Doc's JPO and the modded kernel.
Compared to ther lesser speced phone the SGS is pretty slow so yes it does need a lag fix at certain functions

[Q] Some advice would be nice

Hi all,
I've been following all the Froyo hoo-hah with increasing amounts of anxiety. I'm on T-Mobile in the UK (so don't have it yet anyway) but what I'd like to know from an XDA expert is what's the best advice for me at the moment. The things I'm curious about are as follows:
My Eclair version appears to be JF3, how can I get it up to date?
Is the stock Froyo actually any good and worth upgrading too? - reports suggest it's no major improvement and in some cases actually a step back e.g. increased battery drainage, no GPS improvement, worse lag than Eclair etc
What is the current route (not root) of choice for getting the best performance from the SGS? for example, would the stock Froyo with the voodoo lag-fix be an adequate route or is there something better. If I was starting from scratch, assuming I'm relatively technical, what would you suggest?
Is Odin a better solution than Kies (I'm only using Kies for updating purposes anyway).
Last question, is it worth using a backup app or just a combo of appBrain and Kies?
My main concern is just reducing the, what seems to be increasing, lag on my current version (with OCLF installed). There's nothing more annoying when you're trying to show your phone off than it hanging.
Sorry for all the questions and I know some of you would say "Go search the rest of the threads!" but sometimes that just creates more questions than answers.
I must say though that it seems more and more that Samsung's software guys aren't really that competant.
I really very much ppreciate any help or advice anyone can suggest

[Q] honestly speaking is everybody happy with their phone lagfixed?

heya fellas
question here is with all the lagfixes/kernals
is everybody happy with how fast/reliable the phone is ?
im mainly a tester and was happy since i wont keep a single setup for more than a few days, and since my latest setup,in my situation all it takes is a week and the lag is back ....
wether i was OC'd or not the lag is haunting my phone T_T
current setup is darkys v7 rom and SO 4_5_3 kernal with 1.4mhz set on boot
1 week of normal use with 80 apps installed and lag ranges from 1-8 secs wether it was moving between homescreens/app pages in menu/call log/msgs
last lagfix i was completly happy with was longback when i was on voodoo and OCLF on top of it. i remember the phone was seriously blazing fast like it had everything done before i asked for it, and that setup only lasted a month or so before froyo was out.
i sound like an old hag complaining but seriously who out there is very pleased with a certain setup? anything yall recommend?

I'm on Darky's 7.0 JPY (Have been on Darky's ROMs since 5.1) without a lagfix and the phone is snappy fast, as are all apps I use (about 4 pages of them). Haven't seen it lag in weeks.
Do you face a lag after you launch up multiple apps? Or generally from boot onwards itself?

from boot i know its the media scanner taking over 100% of the cpu
clearing ram clears most of the lag but i notice the crazy lag whenever i have any amount of available ram of 80mb and less
mainly ram jumps between 130mb and 60mb from what i see
got a few widgets to monitor ram/cpu/temp/battery/ and the control widget with 3g/wifi/bluetooth/data/gps/brightness/media scan/reboot and a black background
trying to maintain a small amount of widgets to keep free ram available, pretty much doing my best

I use Autokiller Memory Optimizer with an Aggressive preset, it helps keep multi-task going smooth (Usually have 130~ MB free with it running). Have you tried that application?

Likewise no lag at all .

Most lag comes from bad app.
The only on i can't get lagfree is twlauncher. So i use golauncher instead. I don't se any lag.
I also use ext2 file system.
This with my kernel.
Im happy with this lagfix and i don't think it will be laggy over time.
**Using my own JPX kernel, z4mod, 345MB Ram and ext2 filesystem**

Whilst it never really bothered me in 2.2, in JPX/2.2.1, honestly, I'm not running any hacks. I seriously haven't seen any remotely long stalls anymore. Also, all OS's stall, it isn't only because of "bad apps"; it can also happen when swapping and such. We really don't know enough about the lag problem to say where most lag comes from.
Since JPX also introduces over the air updates (one major flaw with earlier firmwares), if the GPS turns out to perform like fitness-grade GPS (I still need to test that), I'll be extremely happy. But no longer entirely dissatisfied. Taking GPS out of the equation though, I am now happier than I've ever been. If Samsung frees up more RAM, I might even start overlook the GPS problems.
After I test GPS, I'll know for sure.
(PS, I don't use any lag optimisations, because I don't feel they solve the problem properly).

Did you read what this tread was.about?
I can also say with lagfix the phone is better then stock. The latest firmware did alot for the lag, but it still things to do.
**Using my own JPX kernel, z4mod, 345MB Ram and ext2 filesystem**

thanx for all the suggestions fellas
just reverted back to 2.2 (missing darkys already T_T)
will test it out n check how things go
first things first gps surely seems worse than darkys rom for some reason (could it be the modem file ?)

[Q] How many people are running stock ROMs?

I have never found any ROM that runs as well as the stock JL2 (I9000M) I am on now. GPS works great (10 sats seen with 32.8ft/10m accuracy), no lag at all, no nothing, the phone works as advertised. I don't have all the features the other ROMs have, but I don't have any problems either.
Just curious how many people are running stock ROM's.
Ian

ROMs offer more than GPS fixes. I use a custom ROM for its visual enhancements, some bundled features and fixes (like wifi drain, etc.) and lag fixes which are not otherwise found in many stock releases.
That said, if one is comfortable with the performance on the whole, then one shouldn't really bother moving across cooked ROMs -- you're right at that

To be honest I never entirely understood why people ran stock ROMs for daily use. Custom ROMs are just so much more versatile, faster (lagfix!), and generally better, so I see no use in running a stock ROM over a cooked one.
EDIT: Except for ROM selection, I guess.. I don't believe there are any cooked ROMs running JL2 right now. Soon as I get my phone back from repair I'll start workin' on one.

I only mentioned the GPS as an example because this seems to be one point people are having difficulty with. I get no lag with my phone at all so no lag fix is needed, everything works very well.
I do miss some of the extras on the cooked ROMs like the cool multi-colored 'X' at boot-up on Darky's ROM, the extra SGS tools (I did download them separately though), and other stuff.
I did install the Gingerbread keyboard from that ROM onto mine as it's just a simple apk install.

stock
I have stock JPX but with advance voodoo. over clocked to 1.2 gingerbread launcher and keyboard with aosp lockscreen.
used to flash roms on hero and dream and they just lost to many features or after a few month got very buggy so staying away this time.

What is a stock ROM?? I think I saw or heard that thing when I bought my phone 4 months ago
Seriously, if you're happy with what you have, then stick with it

That mod seems to be subjective...thats why I haven't installed any custom ROMs, all the ones I've seen include Voodoo's visual enhancements, but everything on the screen looked slightly over-exposed and washed-out to me.

The only thing i miss with a stock ROM is the superior idle battery life, anything else cant be missed.

See, its a matter of personal taste and preference.
Compare it with a car. You buy a car and some people like it stock and untouched. The stock ride is good anyway and is mostly fine. Some people want to personalize the car and put alloys, change interiors. Some want more performance and put some engine enhancement parts or boosts.
Same goes with your phone. You can pimp it any way you want by using different ROMs or you can stay at stock.
No one can tell you and convince you what you are missing unless you try it.

I've been using stock rom, currently jpo, will upgrade to jpy via kies as soon as I get some time.

I have tried a lot of different roms in the 4 months I have had my phone.
I always found the cooked roms a bit flaky, not too bad, but enough where I always go back to stock.
Is there a list somewhere where I can see the changes between 2.1, 2.2 and 2.2.1?
Thanks,
Ian
PS, sorry for posting in the wrong forum, I'll take 20 lashings out of petty cash.

I'm running with Darkys V7.6 Rom at the moment it is much, much faster then the stock XXJPY and im now running speedmod instead of voodoo and battery life has improved a little.
Overall i think if you can make a rom or use a custom one with all of the required lagfixes and other little tweaks they are far superior to stock roms!

I am a big fan of Stock ROMS in general. The cleaner the better I always say... The new JL2 ROM is very nice. Fast, stable, and works well. I do like to change the home screen for visual stylings.
That being said, I blew my phone up yesterday trying to download 2.2.1 from Kies so I am currently running Darky 7.6.

[Q][i9000] Custom Firmware?

I have the 16GB Vodafone UK Galaxy S. Today I was in a city trying to use satnav and it was rank rotten. So I thought I'd see if an upgrade would do it. I was using the very first Froyo that Vodafone came out with - I upgraded to that and hadn't upgraded since. I did have it rooted and 1 click lag fix was on it.
I upgraded to Gingerbread just there, sadly I had to do a factory reset, however it's all working.
I have realised that if I am going to put a custom firmware on it then now is just the right time to do it.
Is there one out there that's stable, and an improvement over the Gingerbread I'm using? Particularly I'd like it to fix the lag (if that still needs fixed) and even better would be fixing GPS/Satnav.

Pinpong blockbuster rom - ticks all your boxes. Get faster fix from market.
Your gps will never be 100% satisfactory in the city, in fact it will probably always be poor - no matter what custom rom you use.

Have you think about CM7? Great Rom, works well on my phone, and add many new things.

Hi Mate, I tried many custom roms and finally settled for
(ROM)GingerCriskeloV77-9LS-CamHack- SIP + NoIncRing I9000/T/M JVP 2.3.4
Cheers

Well, I managed to get it on. Booting up is weird though, it looks for a long time as if the screen is broken, but eventually ti comes on to the Blockbuster lock screen and then everything is fine. It does seem faster - but I'll only really know when I get to one of those situations where I feel the phone is frustratingly slow.
Thanks very much Woolf!
Time allowing I'll give the other roms a shot, although this Blockbuster one does seem to be good enough for me.

Sadly my phone now reboots constantly. it seems to do it when the screen locks

Check you got the installation right for that rom, maybe you had to flash a jvp stock first or some similar omission?
Sent from my GT-I9000 using XDA Premium App

Sorry to hear you're having issues. Try flashing to a totally stock JVQ first (with repartition) once you've backed up, then if you don't like that, try a custom ROM. I don't think many JVQ custom ROMs are worth trying if you want a taste of custom ROMs. Better to try CM7 or MIUI for something fast and different.
As a side note, the best tip I've seen for fixing the dreadful GPS we have with the i9000 is to buy a Nexus S or just ANY other phone! Yes, some radios appear better than others, but nobody can prove anything and it's almost all subjective feedback. A drop in the ocean of improvement needed for satisfactory function. If you must use it, a bluetooth GPS receiver and 3rd party navigation app seem the best way to deal with it.

I've now stepped away from Blockbuster. Even doing the a perfect install it crashed often and repeatedly. I did try upgrading to the very latest and that crashed several times in the past hour. Part of the problem was the rom starts with a lockscreen that has a messaging unlock on it, but it isn't set to an app that comes with the rom, so it reboots every time. Sadly that wasn't the only problem, as I was still getting loads of reboots.
So that's out of the way.
I'm now a lot more comfortable using Odin so I'll be able to try other options. I'll try the other two suggested in this thread first of all.
Next to test is CM7.
Thanks for the help folks!
CM7 aborted. Instructions are incorrect, the file they say to download doesn't actually match the instructions so that's out. Plus it clearly states it's not suitable for day to day use... so I don't thnk the time in working out how to fix it is justified since it looks like it wouldn't be useful.
I'm going back to the original question in the thread, to say that I'm looking for something stable. I now think that a custom rom is not the way to go. However some modifications may well be.
Can anyone suggest some kind of lagfix/speedup that isn't a complete overhaul like CM7, Blockbuster etc, that is very stable and that'll make my phone faster?
Edit : Part of what I was doing to install Blockbuster was install Speedmod kernel. So I've gone and put that on, and used the clockwork mod to root it, and also convert to ext4. I think things are looking pretty fast so far. I'm not sure if there's a lagfix for this, but I'm quite comfortable just now footering around - unlike the complete rom I don't feel out of my depth. So I think I'll be ok for now.
