[Q] what is swap??

ok.. im a noob at this... bt what is SWAP partition??? how does its size effect the performance??

It's a partition on your device that the system use when the RAM is full.

so if its grater in size.... that means its good... right??
and if so.. then y do devs prefer to keep it as 0mb??

Beceause it's easier to maintain it i suppose ^^

Its because there is no need for swap and it can reduce the life of your sd card, according to most ppl

But remember, swap partition will never be fast like device ram chip.
And if u want to achieve good performance witch swap partition, buy microsd card class 6 (not 4)
good luck

Or use the stock class 2 card

ok... how do i check the class of by card?? coz here in India they dont provide class info along eith the card... also there is nothing written on it.... my card gives me a decent transfer rate of 4-5 mbps while copying to the card...

Class 4, it give me 10mb writing speed
Sent from my HTC Wildfire using XDA App

then i'd say mine is class 2(4-5 mbps while copying pc to sd, where as 9-10 mbps while copying 4m sd to pc)??? any software that could assure me??

interesting I have 8GB sd card class 4 and writing speed is 2mb max... is anything wrong? ****

Either u have been fooled, or its a problem with ur Pc(coz my class2 card gives me 4MBPS),
or the number of files is too large
Example :- 1 file of 100MB will copy faster than 100 files of 1MB each...

Faster SD Card

Does it help more if I buy a new faster SD card (default card is a Class 2 card), or do optimizations such as this one: http://forum.xda-developers.com/showthread.php?t=888379
I'll probably get a Class 6 card, as I haven't seen any Class 10 yet for micro SD.

Yes, faster SD cards do help quite a bit. I used a class 4 for a while and it was noticeably improved for apps2sd on eclair. I got a class 10 for Christmas and the improvement over class 4 was definitely noticeable but not as dramatic. I've read that there isn't much of an improvement between class 6 and class 10 due to hardware limitations inside the phone. For HD video recording I've seen recommendations for class 6+.
Khalpower's optimization script is amazing for eclair. I recommend the JIT, optimized build.prop, overclock and apps2sd. There is also a newer JIT, but I'm not sure if khal incorporated it into his script yet. I think we're still struggling to get the froyo builds to measure up to the optimized eclairs.

Not sure though, I find my XT720 is more compatible with class2 SD cards. I've got one 4GB Class2 Card, one 8GB class2 Card and one 8GB Class6 card which all made by SansDisk. all of these, the most compatible one is the 4GB class2 Card. Although the Class6 card is faster and perform better, there's an issue with stability, where the phone frequently cannot mount the card when the phone is booted.
pls tell your suggestions.

there are class 10 micro SD but the prices are outrageous at the moment.
class 6 16GB is the best bang for the buck right now
the 32GB are still stuck on class 4
looking forward to get some 32GB class 6 when they come out

Thanks for the comments. I think I'll get a 16GB class 6.
32GB microSD are also still pretty expensive (above $100).

Been using the Class 6 for a day now and I can feel speed improvements in loading apps or data from the sd card. I also cleared the factory settings to start fresh.

I've got a class 10 16 GB microSD card for 30 € in Germany, which is about 40 $. I think that's a fair price. I haven't used it yet, so I can't tell you if it is faster or not.

I'm always hessitant to buy something with that odd of a price/speed ratio. I was actually reading the reviews and found something VERY interesting. There was one person who was mentioning an app called SD Speed Boost that was described as being able to adjust the sd card cache, thus speeding up the read/write speed to the card. It was only a dollar, so I tried it.
WOW...
It has improved the speed of my system 10x. I was skeptical at first, but I realized that if I run SD Tools from the market to test the speed before and after, it shows a significant increase in read/write speed. Obviously, those of us who have apps and cache on our sd card are constantly hitting it and the card's performance will affect performance.
Does anyone else want to tackle this $1 app and confirm my findings? If this is the answer to our slowness problems, maybe the settings that this app changes can somehow be added to our ROMs for everyone to benefit!

Is this the app your'e referring to? My write speed stayed about the same @10.7MB/s but the read speed went from @16 to 23 with a 1MB cache. I don't have any apps on the sd card to verify that aspect of any performance boost but Media Gallery loaded pretty quick.

Yes, this is the app i'm using. I've been "field testing" this all day, and I must say that I have never had this type of responsiveness and speed from this phone EVER. I am loving this $1 addition to my phone. I have a class 4 card that seems to be giving me 6mb write/33mb read and that is substantially better. I've tinkered with the different settings and found arount 3000 giving me the best numbers with my specific card. I can only imagine that a different class card would need different settings.

OS: Dexter's 1.3 froyo with bugfix 2

Average result from running 3x:

4096KB cache: Read: 33.67MBps (141% faster); Write: 6.90MBps
Interesting. The app seems to increase Read-speed only. I need to find an ideal cache size for optimal speed increase, so far it seems to be 2MB for me.
I'll rerun with my old Class 2 microSD card when I get home.

I think the app is just changing the value in /sys/devices/virtual/bdi/179:0/read_ahead_kb
The default value seems to be 128. You can set the value using e.g.
Code:
echo 2048 > /sys/devices/virtual/bdi/179:0/read_ahead_kb
I have a 16GB Kingston "class 10" (see also complaints about this card throughout XDA--I got it as a gift and I believe it was on sale for $40 at the time).
I've been testing read and write speeds with "SD tools" (free). SD tools writes and reads 190 MB and displays a dial as it goes so I can see that the initial write speed starts pretty high (10 MB/s) and then quickly falls significantly within a few seconds (probably after an on SD card buffer gets filled) eventually stabilizing at 3.3 MB/s. So, clearly this card is not really class 10 at all as it cannot sustain 10 MB/s except for what seems to be a 1 sec burst. As far as read and read_ahead_kb goes:
128 -- 14.1 MB/s read (avg of 3)
1024 -- 22.4 MB/s read (avg of 3)
2048 -- 43.2 MB/s read (avg of 3)
4096 -- 38.2 MB/s read (avg of 3)
Optimal also seems to be 2MB for me.

SD card speed?

i upgraded to a new SD card and run antutu to see how fast it is but to my surprise this new class 10 card is not faster than my old class 2 card.
so is there like a hardware limit or why could that be?
both cards have about
6mb/s write and
15mb/s read.
anyone got some better results with a class 10 card?

I have a Samsung Plus 16GB Class 10 and get:
According to SD Tools: 12.4MB/s write and 17.2 MB/s read.
According to AnTuTu: 11.3 MB/s write and 14.7 MB/s read.

16GB Sandisk Class 10 (Antutu 2.3.1, 2nd run.)
10.4 MB/s Read
10.0 MB/s Write
The card has 12.4 GB on it of real data before testing.
This is on GR3, which I don't think has any "SD-Card optimization". (Too lazy to check.)
Keep in mind that we don't know, at least I don't, how Antutu tests. If it's testing with a lot of independent reads/writes, the speed will invariably go down. (If copying a single large file from my computer, I get a much higher throughput.)
"Class 10" should only mean that your card is able to sustain 10MB/s of continuous writes, it doesn't say anything about access times/block erase speed (which can influence any benchmark.)

Hi TrymHansen, there is a free app called SD Tools which does nothing but test SD card speeds.
Edit:
FOR ANYBODY ELSE READING THIS THREAD:
The class rating of a card indicates the minimum speed the card will write at. Class 10 = 10 MB/s write speed. Read speeds are usually higher than write speeds.
Anil

Excuse me for being dense, but I don't get the point of your post. I explained in my post what Class 10 means, and then you post as if I asked what class 10 means.

I can confirm the quality of Kingston SD cards. My 16GB "Class 10" gets the following in SD Tools:
Writing Speed: 7.2MM/s
Reading Speed 13.5MB/s
It's good enough for me as I was considering just getting a Class 6 as I don't exactly do much HD video recording, but if you need the speed - avoid this card!

I am using Sandisk 32gb class 4 card.
Antutu Benchmark
SD card write: 5.6 MB/S
SD card read: 8.9 MB/s

Your SD Cache size matters when u perform SD Speed test in your phone. If you are using CM7 ROM, the default is a mere 128kb cache.
Cache size of SD can be from 128kb to 4096kb and different sd cards will perform better/worst with different cache sizes.
Just thought it would be a good info to share.

why is it that im getting two diff figures when i test my card with antutu and sd tools?
sd tools - read 33MBs
write 6.1MBs
antutu read 10MBs
write 2.6MBs
something doesnt add up
sd read is 2046 default on miui rom
my card is a ridata 8gb class 10
which figure could be correct?

This is sort of true, but if it was a mere cache it would always be a good idea to set it as large as you can afford RAM-wize. This is not the case.
It is a read-ahead cache. In short that means that whenever a read is requested, it first checks the cache to see if the data is already there, if not it reads the amount of bytes specified no matter what.
Increasing the read-ahead cache will help when reading large files, since it leads to fewer (actual) io-commands being executed.
However, if you're reading a lot of small files it will hurt performance, since for every read issued it will read a lot of unnecessary data before it can go on to the next request.
(I also think this is at a block-level, which means that it merely reads the next blocks, not knowing if they actually belong to the file you're reading at the moment, but not sure about that.)

The bigger the class, the more performance you get, so you would obviously want to purchase class 10 if you can afford it buy the largest class you can get, though I would suggest *at least* 6

What will you do with your sdcard?
To save music and document, a class 4 is enough. (this is what I use)
If you want to move most of your application to your sdcard get a higher class.
SanDisk make great sdcard if you don't care about money. Kingston is fine. Adata class 10 are great for the price.

This is not true! The class says something about the min performance, it says nothing about the max performance. It is possible a class 6 beats a class 10 card.
So my advice check some tests, where they compare each sd.

get a class 4.
There's a reason why most of the Windows Phone 7s uses an internal class 2 microsd card.
For writing many files onto an sdcard at the same time (lets say while using an app) it would be faster the lower the class.
But obviously a higher class would let you write a single file faster, but with a class 4 you could easily record HD video on your Optimus Black with no lag at all.
Save the money and get a class 4.

Thanks guys for ur suggestions..

Higher class = no problem till now

Sent from my heart into yours

Never heard about higher class card using more power. Unless you keep allot of apps on the sd there shouldn't be issues. The higher the class the shorter will be the response time and higher the read write speed.
As for video keeping in mind that for full HD 6Mbs is enough. Which means that with luck class 4 might be ok. Likely it won't.
I have good results with hd video class 4 on Bada phone, but my OB hiccups with class 6 ( that's still to be confirmed if it is software or hardware issue).
If price is not a issue get the highest possible 10 is about optimal for phone higher than that is overkill.

U wrote so many stupid things that I cannot respond em all, so I will respond one: the only reason why W7 phones use class 2 is that those cards are cheap as autumn leaves.
"with a class 4 you could easily record HD " compare the bitrate of full HD stream with recording performance of class 4 card !!!!!!!!!!!!
euphorcimoron - take in mind one straightforward experience which can obviuously can be seen when You start Your OB ( but some x%$#@* here are to blind to see that ): multimedia files are scanned each time You boot the phone. More files -more time, faster card- less time.
So: get the card as fast as possible: better video recording, apps installed on SD work faster, faster copying of multimedia files into Your phone by any connection ( USB,WiFi), faster booting and so on.

Is there a limit ad to what the OB can actually utilize? I didn't buy a 10 because the sales guy didn't think the phone would have the read write speeds to need that high of a class?

Depends on the bitrate bro, class 4 theoritically have 4Mbps so if your video recording has high bitrate it will slowdown the performance.
Also afaik CM7 has a bug about HD recording.

[Q]SD card acting up...

For a while no i've noticed my SD card getting slower when i transfer files.It's also picked up by antutu as well.It's a class 6 8gb Transcend.I don't use Swap or anything like that since i don't feel it neccesary for my needs.
Scores in antiutu went from SD read (110ish) to 30ish.Its performance has come down to that of a class 2.
Should i format it?What method should i use?
Any other suggestions?

dont take antutu's score very seriously because they are just BENCHMARK they are just tool to know the average performance . performance still depends on how you use it. but you can try reflash rom/ wipe sd using pc or reinstall antutu

Yes, format it.

Go to cyanogenmod settings->performance->scroll down till you see as card cache size.
Set it to 2048 and then reboot.
The read and write speed of your sd card must increase..

I don't take antutu seriously,especially since i get about hte same scores with both top GInger Bread ROMs.But there's a huge difference in performance.
Obviously i should format it but which way is better?Through PC or the phone itself?
PS:FFFFFF i have to find 8gb of free memory D:
