gauging if nfs is slow ...

[K.C. Chan]

Does any know what tools (nfsstat) and how to interpret nfs statistics? the reason I am asking is that I have a suspicion that one of the custom process may be bottlenecking on an nfs mount. Thanks.

Hi,

read this first:

http://www.usenix.org/events/samples/submit/abstract.html

you can google for nfstrace and find it,there are a lot of links.

You could also try this:

Hope that helps.

K.C. you could dd from dev random into a file on the nfs drive and time it, use something like this :

time dd if=/dev/zero of=/mnt/test bs=16k count=16k

There are more examples of performance tuning and testing found here:

and here:
