Hello Roch, It's not my case. NFS stops to service after some point. And the reason is in ZFS. It never happens with NFS/UFS. Shortly, my scenario: 1st SFS run, 2000 requested IOPS. NFS is fine, ;low number of threads. 2st SFS run, 4000 requested IOPS. NFS cannot serve all requests, no of threads jumps to max 3rd SFS run, 2000 requested IOPS. NFS cannot serve all requests, no of threads jumps to max. System cannot get back to the same results under equal load (1st and 3rd). Reboot between 2nd and 3rd doesn't help. The only persistent thing is a directory structure that was created during the 2nd run (in SFS higher requested load -> more directories/files created). I am sure it's a bug. I need help. I don't care that ZFS works N times worse than UFS. I really care that after heavy load everything is totally screwed.
