I'm running steel Droid 5.1 and I was wondering what the recommended VM heap size is for ics. I saw it somewhere a while back but I can't find the post anymore. Also what does VM heap do exactly? What does changing the values do?

I'm not sure what it does, but i know I read the exact same thing. I believe it was 88 (all the way right on ROM Toolbox). Unfortunately, I am only about 70% sure.

I'm running cm7 rc1, I've tried some ultra low, low, and medium voltage kernels from both cor and chevy but haven't found a custom kernal that will run stable. I've also tried the supercharger script, underclocking with setcpu, and using autokiller, but I can not, no matter what I try, keep my phone out of a low memory state and battery life that will last me longer than 5 and if I'm really lucky 8 hours. I'm not using any widgets, I keep wifi, 3g, and gps off most of the time, and have 1/3 of the apps I had on my eris loaded on the phone, all on the sd card. I've tried to recal the batt. but I think the process must be diff for the driod and haven't found a decent guide. Could anyone point me to a decent guied, good tools for saving batt life, and possibly a cashe to cashe script or simular for the droid? I would really appreciate it, thanks so much in advance.

Well, if anyone else has the same issue, I fixed my issues by partitioning my SD card with a swap partition and utilizing swapper 2 to use it. I turned off compucashe, and used the setting in autokiller to speed up r/w speeds on the SD card. I also set autokiller to optimal. I found Chevy's lv .125-.900 works well, I uninstalled setcpu, and set my Max speed @ .600, my min. @ .125 and I'm using the ondemand, scheduler because smartass and interactive seemed to be laggy. the phone runs snappy but battery life still leaves much to be desired, still experimenting with it.

There is so much wrong with this post. I can't explain right now, but you have my word I will tomorrow.

The swap is working, I'm not having mem issues, if I can figure out how to keep my phone from booting while charging and/or how to get it to boot with out the batt so I can recal I think my problems would be solved

What is the Compcache RAM Usage that you find best on your Magic 32b? I am trying to figure out what is best for me.
I am currently using the default 8mb. I do know anything over 20mb causes problems for the browser. I'm still looking for what works the best.

Some one had recommended 16mb and is working really good.

Dont use compcache that ***** slows your phone down.

From one side you are right, from the other side there are no alternatives if you want to run actual ROMs on the G1 with a decent set of background services. The alternative, i.e. running without compcache implies continuusly killing and restarting of apps by Android, which for sure will give you a worse user experience.

I prefer running very low swap (e.g. 10 swap) instead of compcache and that helps a lot..

Hi guys,just wanna ask you all something. What is the most preferred VM heap size for GingerDX? TQ

Default selected is better {32}
Thanks very much. But if I set it higher,will it cause error?
Sent from W8 using XDA App
Wont cause error maybe but i heard larger vm heap size,the shorter the battery life. If im not wrong,the vm is kinda related to performance/gaming
Sent from my E15i using xda premium
It's 32 as default for GingerDX. What about stock rom? Is it the same?

Interested in getting zram for the N7, seems awesome.
Two things: I can't find a flashable .zip for the nexus 7 so it'd be appreciated if somebody could stear me in the right direction with some of those.
Also, when I have flashed it, what values should I set it?
Thanks

Zram is built in on many kernels. You can use trickstermod to turn it on. By default it uses 10% of ram as compressed swap space.
However any real uses for zram were on older devices with limited ram so the performance gain may be negligible at best.

I wish to increase usable ram on AT&T or MR stock.., is it possible? if possible, how?
Um it's not a Computer. You can't just add ram lol.

I know it can done for some devices, and it will be a kernel tweak. But i dont think they will make a significant difference...anyhow, there is none that i know of for ahd..
Disable unused system programs in setting>apps, and remove programs/bloat you never use with root explorer in /system/app.

It can clear used ram a little... but I need to know how to increase it... like 808mb in cm and other custom ROMs...

It not clearing ram, the change is permanent until you use RSDlite. The effect is the same as if you'd do some kernel tweak.

Understanding RAM
I apologize for resurrecting an older thread, but I'm having difficulties wrapping my head around the limitations of available RAM. It seems sadly lacking that the newest devices still have a ~800mb RAM limit, with a good 2/3 being used up by system processes.
In trying to understand the root issue, I guess my first question is why. Why is so little memory dedicated to running apps? Is this similar to the old 640K limitation under DOS? Why can't more memory be allocated to RAM for increased performance when running apps? Please correct me if I'm wrong, but It is my understanding that RAM and Storage (ROM) are physically the same thing, but separated by artificial "partitions" to isolate RAM from Internal Storage. If my understanding of this is correct, why can't one sacrifice Internal storage space to increase the System RAM size to, hypothetically 2gb, leaving roughly 1.3gb free for running apps so task killers or memory "babysitting" is not an issue. Wouldn't this be better and more efficient than just having a mere 300mb available for running apps?
I would appreciate it if somebody could explain and/or correct my understanding of Android memory utilization, and why System RAM seems to be such an issue.
