Description Christian 2011-06-16 21:10:09 UTC 
Having problem with read over NFS, speed does not exceed 300Mbit in our environment. With SAMBA, SCP and other methods we get 900Mbit-1000Mbit in read throughput but when using NFS there seems to be a problem to exceed 300Mbit.
We are using ZFS in our environment but have tried to export a non-ZFS volume with no improvements at all.


Write speed is good, so if we reverse mount export in the reversed way on server a instead of server b we can write over NFS (in the same direction as we would read in our earlier tests) with a throughput at 900-1000Mbit.

How-To-Repeat: Running FreeBSD 8.2-RELEASE
# /etc/export:
/vol1   -maproot=root   192.168.x.x

# mount 192.168.x.x:/vol1 /mnt/vol1

I have emailed the individual and am waiting for more 
information w.r.t. the slow NFS read rate he is experiencing.
