Can you provide a bit more info, in regards on what kind of system VMware Server is running ? Disk layout, RAID, ...
There could be several reasons why the disk queue is so high ...
Windows 2003 SP2
Intel Xeon 2.00 Ghz
8 GB Ram
Raid 5 over 3 disks
The thing is that it worked ok before we upgraded to the RC2 version.
Hope this gives you some more info.
The three guest OS machines are Windows 2003 Ent SP2
Thread moved to Server 2 beta:Performance forum.
I doubt we're going to find a "quick fix" for this, since we're still talking about Release Candidates ...
Did you create the disks with the "allocate all diskspace now" option ?
At first i did not had all disk spaces allocated. Later I converted the disk so that all diskpace is allocated. Trying a VM with the diskspace not fully allocated which runned good with the earlier version the same result shows up (Bad Performance).
After the third server has been started its also so that the host server dies in my hand, I bearly can stop the third machine to get back performance.
1. Use SCSI disks in VM (useing LSI controller).
2. Preallocate (and defragment on host) those disks.
3. If you have enough memory on host (seems you have) add the following strings to the VMX files:
MemTrimRate = "0"
sched.mem.pshare.enable = "FALSE"
MemAllowAutoScaleDown = "FALSE"
mainMem.useNamedFile = "FALSE"
It helped me.
Thanks! Will try!
We found the problem. Somebody changed a setting on the SCSI controller....very nice. The optimalisation for performance was not set to optimize for performance. When I changed it back performance went up like ....
