<br>Hi<br>Here are some tips you could use to improve overall performance:<br><br>16 is a good number to start with. Increasing the number of threads for non-Solaris OS can create performance issues as memory is allocated upfront and threads are activated on every request. <br>
<p class="MsoNormal">Run nfsstat -rc on the client. The value under TimeOuts
should be small indicating a healthy network. Ensure that both server and clients are running the current
NFS version 3 or 4. Can also force server and clients to use TCP like so: <br>mount -o proto=tcp server:/export<span style=""> </span>/nfs</p>
<p class="MsoNormal"> Using the mount command, the read and write blocks can be
increased to 32k for better performance</p>
<p class="MsoNormal">Some recommended values for improving NFS performance: <br></p>
<p class="MsoNormal">MTU size increase to 4000-9000 bytes<br>NFS block size 8KBytes<br><span style="font-size: 12pt; font-family: "Times New Roman";">Increasing hard disk speed by using hdparm</span><br></p><br>
<br>Hope this is helpful.<br>Asaf<br><br><br><div class="gmail_quote">On Feb 19, 2008 1:02 PM, Rob Sutherland <<a href="mailto:sutherland_rob-/E1597aS9LQAvxtiuMwx3w@public.gmane.org">sutherland_rob-/E1597aS9LQAvxtiuMwx3w@public.gmane.org</a>> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
I'm trying to nail down an NFS problem that seems to<br>be related to load and one of the recommendations in<br>the NFS Howto is to increase the number of NFS server<br>instances, which are currently at the default, 8.<br>
Anyone have a rule of thumb for the number of<br>instances?<br><br>The Howto also recommends looking at the statistics in<br>the /proc/net/rpc/nfsd file. I'm not really sure how<br>to interperet these numbers, can anyone point me to an<br>
explanation?<br><br>Thanks,<br><br>Rob<br><br><br><br>Rob Sutherland<br><br>'I is Popeye O'Borg.<br> Yez will be askimigulated'<br><br><br> ____________________________________________________________________________________<br>
