[OpenAFS] improving read performance
Fri, 18 Aug 2006 11:32:34 -0500
I'm using OpenAFS 1.4.1. The fileserver is a PPro 200 with plenty of
RAM and a 3ware card. Write performance is on the order of megs per
second, but I noticed lately (don't know for how long this has been
going on) that read performance over the network is quite bad, about
300KB/sec. Here are the client afsd options:
-chunksize 18 -files 10000 -dcache 5000 -stat 7500 -daemons 3 -volumes 200
The client cache is 256MB.
I tried copying the file from the server locally from /afs to /tmp and
the speed was very good, about 3MB/s. The server's afsd options, cache
size, and client version are the same.
Anyone have any idea what can be improved?
