A couple questions about Swap

I have a couple questions about swap.
I am currently running the swap file from my EXT3 partition on JACHERO. It was all running very very smoothly last night after a fresh format of the sd card and most of my apps reinstalled. This morning I put my music back on the card(6 gigs of music). Right after I did that I noticed the phone ran like a slug again.
So my first question is does the amount of data on a SD card slow the access to the swap space?
My second question is, does the Swap space (EXT3) need to be the first partion or the last? Does it make a difference either way?
Ok I lied, I guess I have a "few"questions.
What benifit if any is there to running the swap on a linux-swap partition as opposed to an EXT3? If there is a benifit, how do I tell Swapper to use the linux-swap partition? IE what is its location?

as far as i know the swap file needs to be last

it should be Fat32/EXT2/3
No, the amount of space doesnt matter as long as you have atleast 100mb free on your ext3 partition.
In the swapper settings make sure the location of the swap file is in /system/sd and not in /sdcard

Ok thanks... I have it set to the last partition already. Swapper is set to /system/sd. I have an 8gig class 6 card. I have tested this twice now though. The moment I put my music on my card the system slows down like crazy, the moment I remove said music it speeds back up....
Anyone have any ideas?

Maybe your ext2 (or ext3) or swap partitions are too big. For ext use 500MB - it's enough. For SWAP don't use more than 32MB.

Thanks but my ext3 is 512 and the swap size was set to 32...

you would have to re-partition your sdcard to include a larger linux-swap partition.

would it be possible for you to give me the code i would type on comsole if i wanted 1gb ext4 and 64 or or of swap?
i have been looking everywhere but i cant seem to find it.
i used 51dustys script for the partioning part nothing on swap in there. it created it for me.

You could use gparted or the partion editor in ubuntu to resize it but it will takes about a half hour to resize and you would have to do it twice since you would also have to resize your ext partion to give you space to extend your swap. It's easier and quicker to just backup and format

ok q. if i go into console and change sd fat32 size to say 2gb. and how would i get ext4 to 1gb everytime i try it reverts back to ext2 i can get ext2 to 1gb but i want ext4. and if i got it like that would the remainder be swap?

You do not need over 500 mb for your ext and anything over 96mb for your swap is quite excessive.

ok i understand that. but with 96mb i would like. its not neccessary for me to have 1gb of ext jst the swap

Either reformat or download either gparted or ubuntu and make a live cd and use either one to resize

thks everyone for info
shold have retraced steps
51dustys script has all i need to complete swap. il try it out monday. also his script will do the format for you from console.

i know you have already found your answer, but i used sdparted to partition my card and it is very simple and easy.

I'm using a 1gb sd card with dwangs superD and it is partitioned, but.....?

This is probably a dumb question. Do I need to do anything different to enable it to utilize the sd card to run apps off of it or is it built in? I read that cyanogen's rom was built in like that. I keep downloading apps and I don't want to run out of memory on the phone. Do I need to do anything to also use the sd card as ram?

I am using SuperD and jus partation your SD card and should all go well

Yeah it is working fine.

I was just wondering if I need to do something different or is it automatically using the sd card as ram and runing apps off of it.

What do you mean by "something different" Different from what? In order for CM to automatically do apps2SD you need to have an EXT partition as your second partition. This can be an EXT2, EXT3 or EXT4 type partition and can be easily created by using the latest Amon_Ra Recovery Image (available here http://forum.xda-developers.com/showthread.php?t=566669).
Nothing else is needed. I see most signatures showing 512MB of EXT partition. I use the same and it has been more than enough for me.
Also, it is recommended that you use a class 6 SD card because the class 2 that came with the phone may not be fast enough and may cause some lag.

Thanks QMAN.

I think you answered my question perfectly. When I put the Dwang rom on and updated to Amon Ra Recovery Image I followed instructions that had me partition the sd card and put ext2 or ext3 type partition. If I buy a class 6 SD card I imagine I can just partition it and put it in.
So to be clear, does then enable the apps to run off the sd card or to install onto the sd card and run off the card also? I mean is it using the sd card as some sort of ram or is it just using it as more of a hard drive? I'm going to guess it is just as a hard drive. I didn't designate anywhere to tell the phone to use the sd card as the installation place for apps. That's why I am kinda wondering.
Thanks

It will both install on and run from sdcard. you don't have to enable anything.
dwang's rom does it automatically as long as you have the ext partition. His however does not support ext4.

Ok great.

Is there a way to see how full the partitioned part of the sd card is getting? When I use settings I can see the fat 32 part I believe, and the internal phone memory. I have Astro, but I don't see an option to view the entire sd card's usage.

In rec mode goto console type...
parted dev/block/mmcblk0
print
this will tell you how much space is used by each partition
Is that what you want to know?

Go into settings and look under sdcard and phone storage.

With Dwang, you can still see 2 partitions, not all 3.

ok

That is exactly what I wanted to know. If I keep installing apps till it runs out of memory I'm guessing I won't know till it says it can't install anymore at some point.
Hey Djn I can't see the partitions with Dwang or do I need to specify something. I only see total space 449mb(i'm guessing that is the fat 32), available space 334mb. There is the internal phone storage section also.

this is what I see
number start end size type file system
1 512 472 472 primary fat 32
2 472 984 512 primary ext2
3 984 1016 31.8 primary linux-swap(v1)
So does it mean I've only used 40mb from fat32 section, but I believe I've used more than that? The ext2 part ended with more than it started, so does that mean when I partitioned it, the memory was increased? From number 3 it looks like 32mb was taken right off the top for ram?

Crap!, Ace is right, you can only see sd and internal with dwang, sorry about that. I haven't used dwang in quite some time.
P.S. Sorry Ace, My bad

Hey Ace

Can you tell me what that info is telling me? It is a couple posts up. I understand the total sd card, -32 for swap yada yada. Just not sure if when it says "end" if that means that is what I have available now.

1 512 472 472 primary fat 32
2 472 984 512 primary ext2
3 984 1016 31.8 primary linux-swap(v1)
Block Start End
Well the above tells you what its for, and amount of space for each partition from starting point to end. 1 app is less than 3MB excluding games so if you have 150 apps you still have a good deal of space left.

Thanks Ace

I don't put mp3s, so other than wanting a little faster load app speed with class 6 I am probably fine with my 1gb class 2 for now. I think most of the apps I have were less than 1mb. I imagine games are larger. If I happen to add mp3 and games will the phone warn me as I get close to filling up the sd card?

Music/vids/pics/docs will go onto the Fat32 partition...So your comp or phone will warn you that the FAt32 is full.

uestion about when you partition the SD...

I followed the [GUIDE] The Ultimate Beginner's Guide {Downgrade, Root, Partition, ADB, and MORE!} and I'm curious abut the Partition your SD Card to have EXT3 and Swap section. When you partition it. it says to set those given values to these...
- SWAP: 96 MB
- EXT: 512 MB
- FAT32: Rest of SD Card
But since I'm using a 16GB microSD, should I still follow those exact same values...?
Note: sorry for forgetting the "Q" in the title... stupid key on my keyboard is acting all funny...

sure, see ext is for apps2sd. Fat32 would be for what you see on your computer when you plug the phone in. I recommend 128mb swap. Happy rooting!

Sweet, okay. Thank you

how can you tell?

how can you tell if your ext partition is helping?
so i downloaded apps2sd and repartitioned, but nothing is faster, i see no clarification of speed from it at all....the only thing noticeable is that my 4 gig sd card is now 1.75 gigs......help?

You don't, apps2sd puts your apps on the sd and that is all. It doesn't help with the speed or anything else.

I think you can check sd storage via settings or type df in terminal to see if its being used and how much space is left.
But speed wont be faster or slower with apps2sd.

the ext partition is for using apps2sd, so it will make your fat32 partition for media and such smaller. swap partition is to make things speedier, or supposed to. check settings/sdcard & phone storage/sd card secondary. thats how i could tell by total and available space

so to have 2 1/2 gigs for apps is really a waste unless i want to have 500 apps on my phone......good to know, if i may ask, how do i get rid of that? and how do i get this "swap" partition?
thanks for your replies, theyre greatly appreciated

You must repartition your sd with recovery and choose a swap size...But all your files on your sd will be deleted from your card. And you must re-DL apps from market.I use 256MB Ext cause i install less than 30 apps.My fav app is gameboid/Snesoid so i mainly care if that works.

*boots into recovery and actually reads the options* oh look, "partition sdcard," am i blind or what? lol. thanks ace, had a feeling i could count on you.....thanks to everyone else for there responses as well ^_^

i used droid swap, but ive only got the stock mem card for now as my 8g **** out on me, and its a class 1 i have been told, which is why i was lagging so much with a2sd. but im pretty sure you can use scripts and such to turn swap on
