no. It will make a difference.

Okay now I'm confused, and I don't mean to hijack this thread. Based on the other persons comment, page pool is like the pagefile.sys file in windows. Instead, it uses the internal storage card for virtual memory as opposed to the physical memory in the phone. If that were the case, there would not be any memory issues with lets say the mogul which only has 64mb. Am I right?

Its not using the memory from your storage card, it is taking it from the available ram.

Now I understand. Thanks.

Your welcome.

could you please upload a 36mb dynamic pp of JD new 6.1 rom? Thanks! I tried learning how to hex change it myself, but i do not understand what numbers i need to put in to make it a 36mb dynamic page pool.

NM, i think i figured it out, i would change those two strings to start with 09 15 i believe.

This thread kills me...

exactly, assuming nothing goes into a low power mode (which it won't on these devices), none have "startup" costs, and none have "stopping" costs.

In a pc if you watch the voltage of your ram they are identical between a 512mg chip and a 4gb chip.

well, that's because voltage is clamped. Current will vary (and, of course, die density will play a big role in that). But again, we aren't talking about adding/subtracting chips when pagepool is changed.

and finally....the pagepool is nothing like the pagefile on a regular operating system. A pagefile on a regular os is used to create virtual memory, by mapping through a slower and cheaper medium. By contrast, the pagepool is little more than a cache of static code portions. The nice thing is, even with a giant pagepool, you'll still have more ram available on a touch pro than many WM devices possess. I expect we'll see a lot of new software that needs that extra memory, however, and your giant pagepool will have to go.

Good stuff ggurusa. I noticed the same crappy battery life when I used a higher page pool. I guess I'll just use a 48 mb Page pool then if it makes no difference. Even with such a high page pool, Tf3d is still slow...

Anyone have any thoughts on this? Hasn't been a post in a few days. Does dynamic give any more performance over static? What is everyone's favorite value? I see 36 and 48 mention more it seems?

can anyone change the pagepool on jd's7.1 (not 2.0/3.0) to different sizes to try? i would like 24 or 32, not sure which is better.
