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.
What exactly is your test?

--b.

Sorry for the late response. I'd 200+ unread mails.

I'm writing a large file to the mounted loop device.
