Subject: NFS Read Performance

we're conducting SPEC SFS97 benchmark runs
to evaluate Linux performance as NFS file servers.
It is observed that an unusual high percentage of
benchmark time was spent in "read" operation.
A sampled workload consisting of 18% of read
consumes 63% of total benchmark time. Did this
problem get analyzed before (or even better :)-
is there a patch) ? We're on 2.4.19 kernel- NFS
V3 - UDP, with EXT3 as local file system.

Thanks in advance.
