Hi!
I searched the web for hours, trying to solve the NFS/ZFS low
performance issue on my just setup OSOL box (snv134). The problem is
discussed in many threads but I've found no solution.
On a nfs shared volume, I get write performance of 3,5M/sec (!!) read
performance is about 50M/sec which is ok but on a GBit network, more
should be possible, since the servers disk performance reaches up to
120 M/sec.
Does anyone have a solution how I can at least speed up the writes?
What's the write workload like? You could try disabling the ZIL to see
if that makes a difference. If it does, the addition of an SSD-based
ZIL / slog device would most certainly help.
Maybe you could describe the makeup of your zpool as well?
