Miscellaneous Utilities : RamMap - Nonpaged Pool

Here's what part of the rub is. The system makes this big huge nonpaged pool, but nothing ever shows to actually use a whole lot of it. It's as if the system looks, sees the 32GB of RAM, allocates a huge portion (not maxed) to be used, but never frees it up for use. It's just sitting there in case I need it. I never approach the max of the machine, so I never do. I'd probably be better off yanking my sticksout and replacing them with 2gb sticks X 4.

 

That's what I suspect, anyhow. I think we had a couple leaks to deal with early on, but since then it seems to be behaving.

 

The other comment which I think I need to think about is at the very beginning of an article that I cannot find right now, but was written by one of the sysinternal founder creator types. He mentioned that memory manager or whatever creates the nonpaged pool will create a bigger one if there is an excess of interrupts and DPCs. I'm not sure what is excessive. I run at 0.01 - 0.02 CPU most of the time on interrupts. Maybe I have an issue there? Is that a lot, considering it's a percentage of a very powerful machine?

 

EDIT: If the nonpage pooled is based off algorithm and otherwise doing it's job, given my excesses of the machine, perhaps circumventing the algorithm is the step needed? Alternatively, if I knew what the LiveKD did during it's big dump that dropped the nonpaged pool down .80GB, if it's a command-line action and is otherwise a safe thing to do, I could create a bat file and point to it on start-up. I certainly would not want to run a 15 minute dump on start-up, but a 10-120 second process is just fine if it works. Just a thought. :)
