Can you produce the same test for replicate, too?
A really interesting setup for people who want to get rid of NFS...
In theory the minimum time (caused by a FE network) should be below 23s for
read and write or maybe 46s for replicate write case. I know you have GBit
ethernet, but your disks won't cope with that anyway, so one would be content
with a factor 2 in real life. Nevertheless your test really shows that NFS is
not that bad.
A local-disk FUSE fs would be an interesting comparison, too.
