Hi,
I'm trying to increase the poor performance of my NFS servers. I've
tried to use the TCP type mounts, and tried using r=8192 and w=8192 to no avail.
The present stats I get are:
-------Sequential Output-------- ---Sequential Input-- --Random--
-Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks---
Machine MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU
nfs-mount 1 106 5.8 123 2.2 132 5.3 567 30.5 5988 92.2 127.3 27.2
-------Sequential Output-------- ---Sequential Input-- --Random--
-Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks---
Machine MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU
local 1 1143 93.1 2216 84.7 1762 92.4 1893 94.3 6349 100.0 579.2 81.3
These benchmarks are very bad as you can see. What can I do to increase the
performance of my mounts? Any help is greatly appreciated.
