I've found the best client measurement tool is IOzone, given that 
it measures varied access types (serial forward and backwards, 
random, even jumps, etc.) across various file sizes, and can put
the output into a nicely readable excel graph.  Its available at
http://www.iozone.org/

I also have IOzone packaged up in a test & measurement package that 
has a gui front end (although you still have to figure out which
of the 50+ options in IOzone you want to use).  Its at
http://sourceforge.net/projects/nfstestmatrix

Finally, take a look at the performance howto, which discusses 
various benchmarks among other things.  Its at
http://nfs.sourceforge.net/nfs-howto/performance.html

Tom
