Doug, I'm not familiar with the evil zfs tuning wiki mechanism. I'll have to see if Google can help me find it. As for the ZIL+ L2ARC on the same SSD potentially being the problem, clearly I can't say with 100% certanty that it is not a problem however I have a second host (running 151022) with _exactly_ the same configuration of hard drives + split-SSD and NFS writes to that pool are fine. hvfs2 is ~18 months old but the chrup0 pool is a few months old. time cp -rp /misc/fs1test/004test /misc/hvfs2chru/omics1 real 3m11.431s user 0m0.177s sys 0m28.030s time cp -rp /misc/fs1test/004test /misc/fs2test/omics1 real 21m13.412s user 0m0.188s sys 0m28.678s nomad _______________________________________________ OmniOS-discuss mailing list OmniOS-discuss@lists.omniti.com http://lists.omniti.com/mailman/listinfo/omnios-discuss
