Hi!
Great job with NFS server, it surely is fast, but not on loop devices.
If I loop mount a file and share the mount point over NFS3 or NFS4, the
write performance of the client on the loop mounted share is pretty bad.
On a 100 Mbps (or 12.5MBps) full duplex Ethernet link, I get ~8MBps
speeds, whereas on the loop mounted device, I get at best 6MBps.
Any ideas why?
My server configuration (NFS4) --
anonuid=1000,anongid=1000,secure,no_subtree_check,rw,fsid=0,crossmnt
My client mount options --
rsize=1048576,wsize=1048576,async,hard,timeo=60,retrans=2,actimeo=900,retry=2,lookupcache=pos,nfsvers=4,nolock,intr,noacl,rdirplus
