I am looking into what I think is a performance problem on my NFS.
While copying a file I can see the following:
- kB per operation go from 1024 bytes down to 4.28 bytes per op and anywhere in between
- RTT (round trip time) avg of 50ms
- kB/s avg of 60kB (decrease to 15kB when 4.28 bytes per op)
If you can help me with where to look I sure would appreciate the help.
Also, if you have articles for me to read (for nfs config of parameters, etc) that would be great as well.
