Hello everyone!
I am trying to understand the output of nfsstat to better understand and tweak NFS performance for our machines.
Following is the output from our Solaris 9, NFSv3 running server:
I am concerned about the "badcalls" for "Server nfs" output, is this normal or something is wrong. We have some of our clients mounting the exported File system with rsize & wsize = 32K, Could this be the problem, is there a way to narrow it down?
Any feedback is greatly appreciated!
~thanks ~al

I would suggest asking the Solaris folks for the interpretation for the
output fields in the Solaris version of nfsstat.
That said, the number appears to be a small percentage of the total
number of calls as to not worry very much about.
