Guide to changing your pagepool

What leads you to that conclusion?

I'm not sure I understand your question...

How do I know I'm running a Dynamic pagepool? Or how do I know it's set at 0MB?

I know it's at 0MB by comparing memory sizes; I know it's running Dynamic by observing changes in program memory and performance.

There's also no reason that I can think of why a Dynamic pagepool would be limited to 4MB increments or why a Static pagepool would be limited to 255MB maximum pagepool size but a Dynamic could have up to 1020MB.

Nothing else holds water.

Having stated all of that I'm still going to look for the file.

Reading this thread made my brain leak out of my ear...Just so I'm clear, is there a way to change the static pagepool size on the touch pro?

short answer, yes

How do you know that setting it to any value means it's static? (vs dynamic with a min or max as specified)

The only reason I can envision for the maximum is simply because of storage size for the variable. The 4MB increment is probably related to the sizing algorithm.

We seem to be going around in circles here and to be honest I've not had time to dig around over at Tech Net but here's my reasoning.

The OP assumed that a setting of 15 in the second field would result in a dynamic pagepool while a setting of 16 resulted in static. My assertion is that the values in the second field simply dictate the algorithm the OS uses to set the pagepool size and by definition if you've got a set size it has to be static. I'm inclined believe that FormerPalmOS is correct and that manually setting the pagepool size to 0 results in a dynamic pagepool for a couple of reasons. First, because I can see that there is a pagepool of some size based on memory usage. And secondly because I don't think your phone would perform very well without any pagepool; mine does and though I've only compared it against a static pagepool of 12MB I see no performance impact.

Anyway, to truely this question I just need to find the pagepool on my phone and observe it changing in size. If you can point me to the correct file I'll be happy to do that but as I said earlier I haven't had time to pursue this.

What string I should look for if Im using Build OS custom ROM with default pagepool.I can not find even a half of 1 that posted...
Pagepool changer showing 12mb,but I want to try set it to 0...

almost every rom out now besides stock are modified to use the pagepool changer. you can set it to zero with the changer and it will be dynamic.
