Greetings, I'm attempting to use an OBSD 4.8-stable machine as an NFS
server for storing snapshots from an ESXi 3.5 server. Unfortunately my
NFS performance seems relatively poor at about 55 Mbps (6 MBps). Both
machines are linked up at 1 Gbps via an HP ProCurve 1850G and I'm
writing to wd0. I've looked at disk i/o, upped
net.inet.tcp.recvspace/sendspace (NFS session is using TCP) and done my
share of googling, but I'm at a bit of a loss on how to figure out where
my problem lies. Any pointers would be appreciated.
