Swap

[GroovyG]

As we are all well aware, our XT doesn't have endless amounts of RAM. After a fresh boot I have around 120MB of RAM available, which quickly fills up when launching multiple large apps. When filled, things become sloooooooooooow and annoying. Now I could just ditch it and get a new device with more RAM, but then again I didn't spend hours making the fast "flawless" ROM to be outplayed by the RAM.
The solution: Swap!

What you need:
- A fast SDHC card (the faster the better obviously)
- A kernel with swap support
- The app "swapper"

Great thing is, you can create the swap file on a FAT or ext partition. Set the size, format it and you're done.
I use 256MB of swap on a class10 card - and now even the biggest apps just fly

Also, remember SD Cards don't have infinite life and every write counts; using swap on it might reduce it's lifetime. But then, you probably won't be using your XT anymore when it fails because of this

[GroovyG]

True, but with the expected cycles to failure being in the millions with current flash cards already, both the cards and the phone will have become anciently obsolete well before even coming close to failing

[MENTION=3226614]GroovyG[/MENTION], mm, i saw it before (i had swap on my Motorola Zine) but i heard somewhere that it might slow some android phones so i never used swap...

PD: A class 4 SDHC will work fine??

Put it together with this and see what you get - [SCRIPT] The Best RAM Optimization

Your method looks good, [MENTION=3226614]GroovyG[/MENTION]. I'll try it first.

Probably swapping on that card will slow down things. But you never know, try and see

Tryed at 256mb, and some things are more fluid... like opening the app drawer animation, oppening an app animation, etc... even tested a game (cut the rope) and it seems to be more fluid...

Not all of them would help with swap, and even be counterproductive as they aim to keep RAM free by closing apps.
With swap you want the exact opposite, keep everything in RAM/swap so there's no need to actually close anything - thereby gaining the extra speed. All of the useful VM tweaks are already in the ROM.

It will of course work with a class4 as well, just the gains in performance won't be that substancial.

What do you think on a thirty two Gigs? Haha Just saying...

32G doesn't say anything, It might be Class 2

i hav like 80mb of phone memory available, is it possible to use about 50-60 of phone memory instead of SD card ?

I really wouldn't, stressing it too much could cause bad blocks on it. But as technically possible, yeah you can. You would need to create a zero filled file with dd on there and then use that as swap.

What you can do to free up more phone memory, is moving some apps to the system partition. The app "System App Remover" can do it for you, it's quite useful for large apps that don't get updates very often, like office and such.
