I have moved many VM's from earlier versions of proxmox to proxmox 2.0 I have noticed that the performance has gone down severely. I initially thought it was the local storage but have noticed the VM's that are on a san (as they were in proxmox 1.9) have the same performance issues. Here is output of pveperf pveperf CPU BOGOMIPS: 230368.98 REGEX/SECOND: 745583 HD SIZE: 94.49 GB (/dev/mapper/pve-root) BUFFERED READS: 336.98 MB/sec AVERAGE SEEK TIME: 21.13 ms FSYNCS/SECOND: 28.45 DNS EXT: 72.28 ms DNS INT: 133.99 ms I have seen other posts where FSYNCS should be higher. Is there a way to fix that? Here is a pveperf on one of the san systems. I notice that the fsyncs are higher .. i am not sure i did the command 100% correct. pveperf /dev/san5 CPU BOGOMIPS: 230368.98 REGEX/SECOND: 716351 HD SIZE: 43.26 GB (udev) FSYNCS/SECOND: 39415.02 DNS EXT: 96.40 ms DNS INT: 63.55 ms Even though they are higher the VM performance seems to be the same. For example it used to take about 9minutes to install windows 2008 in proxmox 1.9. Now it takes about 50 minutes. This dosn't matter what storage I use. pveperf information might be skewed because there are close to 100 VM's running on the system right now.
