It's like changing the resolution. Some apps won't display correctly though.

----------------------

For everyone saying they don't see a difference, go into the Task Manager to kill all running tasks. Sometimes if there are a lot of apps running it keeps you from seeing the speed boost. Then trying scrolling through your home screen.

finally got the settings to stick. i got busybox from the market and reflashed root with the fixed zip thinking that may be the issue.

blade buddy still won't reboot my phone though, if i use the save(reboot) option i get an error "IO Exception: not root?"
and if i use the reboot function it just hangs on the rebooting popup.

Mine was already set at 64 because of the custom Tom. But I bumped mine up to 88 and there is a difference. Def not placebo

Is this number safe if your rom is originally set to 32? Heck with it I'm gonna try it.

EDIT: didnt see much difference..going back to 64m

    Being a high-memory device, I'm surprised HTC only set the dalvik virtual machine heap to 32MB, which is fine for 512MB phones. But we can bump it up to 48MB or 64MB without a problem. Each app you run is in its own virtual machine. Heap is the amount of memory each app has allocated to it. If you higher it (if you have enough RAM, which we do) it will result in less garbage-collection, which means improved speed and sometimes battery life.

    If you're rooted on stock ROM, you have to install Busybox manually. Go to the Market and download and run Busybox Installer, then reboot. After that do these steps:

    1) Download Blade Buddy
    2) Advanced Settings
    3) Check the first box for hardware acceleration
    4) Scroll down, Dalvik VM Heap = 64M
    5) Hit Save -> Yes, then manually reboot. If you hit Apply, it's temporary until reboot.

    Goodbye lag. You'll notice Sense is a lot quicker, especially scrolling through the app drawer.

    Hell with the heap ... When's the ROM dropping LOL

    We've got 90% of the features we planned for Warm TwoPointThree RLS 1 implemented.

    Theming and the polish is still left which may take another week or two.


    It's the opposite for me. Everything, including the ROM itself, loads faster at 64M. I haven't really noticed any negatives. Maybe it was the tweaks you did to the ROM? I'm on ViperROM and even with the stock kernel I notice a big, visible performance boost at 64M.

    It may have been the tweaks. I've added a ton of them and they may contribute to the experience.

    For now I'm sticking with 32. Would definitely welcome everyone's input once we start the beta testing.

    Guys be careful of this setting as higher numbers dun necessary equates best performance.

    Your memory is like a huge blank page of paper, the cache determines how many "words" can be written on a page before the system turn to another page. So more words, less pages, less words, more pages.

    Paging cost responsiveness so you wouldnt want the system to turn too many pages but too many words on a page also costs CPU time to read thru the whole page.

    Basically that is the concept so hope you guys can find the optimal value for optimal performance. :)

    Just my 2 cents.

    I did some extensive performance testing this weekend and at least on Warm TwoPointThree, 64M cache was actually too big, hindering performance.

    I've got it set back to 32M and it "feels" snappier to me.

    Was wondering if anyone else has done A/B testing between 32 and 64?

    I get this error too and I have root.

    If you're rooted on stock ROM, you have to install Busybox manually. Go to the Market and download and run Busybox Installer.
