Description of problem:
have been running the 2.2.x series and then the 2.4.9 series kernels for a long
time with no performance issues. i then upgraded to 2.4.18-19.7.xsmp and saw a
very large drop in i/o performance.
i am running a single server (nfs and imap) with multiple nfs clients. the
server seems to be choking on disk i/o.
the server is a dell poweredge 2450 (with perc 3/si raid 1+0 using the aacraid
driver), 2x733Mhz PIII, 2GB RAM.
i'm running the ext3 filesystem and most mounts use the "noatime" option.
where there significant changes to NFS, aacraid, or file caching going from
2.4.9 to 2.4.18?
any tips for troubleshooting this?
