Nonpaged Pool Memory Limitation

Hi All,

I want to allocate two 1MB non-paged pool memories in my driver (using
ExAllocatePoolWithTag). one for read and other for write.
I would like to know what is the limitation of nonpaged pool. Is this
dependent on physical memory?

Actually, I have the option of using single 1MB pool both for writes
and reads. I would like to know if the system be degraded (in terms of
performance or anything else) if I use two pool memories instead of
one pool memory?

Thanks and Regards,
Kid
