Use MEM_64K_PAGES?

[runewalsh]

I’ve been working on the FPC memory manager for some time and noticed that MEM_64K_PAGES speeds it up by 300 ms per GB touched (Windows 10 x64). Have you tried that? (Wonder why they don’t transparently enable it for all VirtualAllocs that qualify.)

I had not yet considered this at all. This might be a good fit for release builds where we need no guard pages and would split up the 64K pages. I'll do some experiments. Thanks!

Ah, nice to see some Pascal code :-)
