thanks for all of your replies!
i solved it by change the page file's size to 4gb (instead of the recommended 24gb) ... that smoothed out all the problems i had!
Not sure why that worked, but I'm glad it seems to be helping you.
Your page faults have nothing to do with your page file in a NUMA arch. It is a result of a CPU hitting the address space on one DIMM bank and missing --- and having to go look in the other DIMM bank.
I explained the issue to you in your other thread, and don't know why my post in this thread was deleted. I love to hear the Mod's explanation for that.
