Slow nfsd write performance, tweaks needed

[Mark Schouten]

Hi,

The box is stable, but performs terribly. Surely, I'm doing something wrong, but I would like some tips and tricks to speed things up. 




So I upgraded to 10.1:


iscsi: 
  1m58.694s
Linux nfs:
  4m37.826s
ufs via nfs:
  2m49.135s
zfs via nfs:
  4m22.415s
zfs with sync=disabled via nfs:
  2m26.411s


Please note that this is *with* sync on the Linux NFS Client.


So this line in the 10.1 releasenotes actually means a lot:
"Kernel RPC code, which is a base of NFS server took multiple optimizations, that significantly improved its performance and SMP scalability. (Sponsored by iXsystems)"


So, indeed. Thanks iXsystems :)


Met vriendelijke groeten,
