Hi,
We've been running some benchmarks on both local and nfs mounts. The
read and write speeds are comparable, but creating and deleting small
files is much slower over nfs than it is locally. Is there a patch to
fix this problem?

No. This is the nature of NFS. A file create must be synchronous with
the server. Data writes don't (in NFSv3).
Creating lots of little files is *the* pathological case for NFS.
