[mythtv-users] diskless frontend nfs throughput

[Dan Littlejohn]

I have a gentoo diskless frontend that mounts using nfs and it seems like
the throughput of nfs is slow.  iperf show the network able to push 770 Mb/s
and hdparm shows the sata disk on the server at 90 Mb/s, but doing a dd
across the network only shows up as 10 Mb/s  (is about 40 Mb/s when the same
test is done on the server to a third machine).

Odd thing is that the pxeboot mounts nfsver2.  Not sure if this is a problem
or not, but other mounts after boot mount as nfsver3.  Really seems like it
is a config problem with nfs somewhere, but I have not found anything that
makes a difference.  Doing rsize=8k,wsize=8k, noatime, async.  Anyone have
any tips to look for or is this 10 Mb/s really the throughput I should
expect for a diskless frontend?
