I am troubleshooting NFS performance issues on Linux, and I'm looking at the following
host:/path mounted on /path: op/s rpc bklog 96.75 0.01 read: ops/s kB/s kB/op retrans avg RTT (ms) avg exe (ms) 86.561 1408.294 16.269 0 (0.0%) 34.595 89.688 write: ops/s kB/s kB/op retrans avg RTT (ms) avg exe (ms) 10.113 326.282 32.265 0 (0.0%) 19.688 72446.246
- What exactly is the meaning of
avg RTT (ms)and
avg exe (ms)?
avg exefor writes is 72 seconds(!) -- would you say this is abnormal and, if so, how do I go about troubleshooting this further?
I'm using NFS over TCP. Both the client and the server are on the same GigE LAN.
