Hi.

I have two machines one running 4.6, the other running a recent
snapshot of current. tcpbench reports maximum throughput of 275 Mbit -
that's around 34 MB/s between them over a gig-E link. What should one
expect with an el-cheapo gig-e switch and 'em' Intel NIC and a  msk
NIC? Is that reasonable or too slow?

The 4.6 machine has a softraid mirror and can read off it at around 55
MB/s as shown by 'dd', and the -current machine has an eSATA enclosure
mounted async for the purpose of quickly backing up to it, that I can
write to at around 45 MB/s as shown by 'dd'. However copying over the
network to it - through NFS I can only get around 15 MB/s. Where is
the bottleneck?
How to fix??

Copying with rsync over ssh is even slower due to rsync and ssh eating
quite a bit of CPU - but that's to be expected.

Thanks a bunch.
