NFS small files

[Peter Hessler]

I'm setting up an NFS server to be used for compiling, and it seems that
while speeds are acceptable for large files, small files take much
longer than expected.

Copying 10000 16K files (in a directory) takes 54seconds, while copying
a 170M single file takes 5s.

Are there any tricks for speeding up small file performance?  I'm
willing to give up large file performance.
