That's correct. RedHat Enterprise Linux 5.5.

I was thinking of trying 1.5.x, but my brief first attempt at making an
RPM failed.

If he is using windows clients then my advice is probably moot given the
new development. I have a feeling he is using linux/*nix based apache
servers to access /afs though?

With 1.5.x, the performance difference between disk cache and memcache
is significantly smaller, particularly in use cases which see a large
percentage of cache hits (such as this one).
I made significant changes to the way we use the Linux page cache and
interact with the backing filesystem, so that our performance when
serving files which are held in the local disk cache approaches that of
the cache filesystem itself, rather than being several orders of
magnitude slower.
Cheers,
Simon.
