performance problem (memory management?)
Hi,
I just installed windows 7 rtm 64bit and I really love it. But i got a performance problem under certain circumstances and hope u can help me
First, here is a list of my relevant hardware:
AMD X2 4200+ @2.7 GHz
3 GB DDR RAM
System drive: 2 x 250 GB (raid 0, about 90 MB/sec reading)
graphics: 9800gt
2 USB Flash drives dedicated to Ready Boost (2 GB and 512 MB)
Now let me describe my problem: I have to run 10 virtual machines on this PC. I use VMWare Server, each virtual machine is set to 128 MB RAM (lowest value possible, any lower values result in excessive swapping). All virtual machines are set up on another harddrive (200 GB, about 40 MB/sec reading), so they don't affect my system drive.
Performance is normally just fine in Win 7 (the virtual machines eat up very little CPU power). But when i use very demanding applications, e.g. Crysis, performance becomes a nightmare (framedrops, game is not playable). The LEDs for my flashdrives and my harddrive are flashing all the time. I guess all my Ram is used and win 7 swaps the data needed for crysis instead of swapping my virtual machines. Only way to play crysis is to stop my virtual machines (which is not acceptable).
In Win XP that wasn't such a big problem, there was some swapping for about 1 minute when i started crysis, then performance was just fine.
Any hints?
