The allocation and swap algorithms were redesigned in the Windows 2008 timeframe. I can't really tell you (because I've not seen anyone do any exhaustive tests) whether they are "much" or only "marginally" improved. I know this is a major issue for the "many cores" work being done.

I know "system managed" and/or different min/max used to lead to performance problems. The system would waste resources constantly constantly growing and shrinking the page file. Plus, that led to page file fragmentation, which really drags a system down. RAM is huge these days, but hard disks are even more huge. I think it would be best if Windows were to just allocate a huge contiguous file and be done with it. That would avoid the overhead of page file management, and avoid page file fragmentation. I/O is usually the slowest part of the system, so you want to avoid hitting that whenever possible. We've usually got HD space to spare. -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
