All,
Thanks for the help! I will look into these.

Some other tools that are useful for diagnosing performance issues:
On Windows:

Especially the Process Explorer which can display the I/O usage of a
single process in real-time.
The Windows Server Performance tool
On Linux there are various hard-to-use tools that write a bunch of text
(sar, var, etc.), but I haven't tried these for several years, so maybe
they have nice GUI's now.
For Java there are several profiling tools. I've had good luck with
JProbe from Quest. Eclipse also has one (install the TPTP plug-ins), but
I found it to either lock up or be difficult to get the data I
needed. And don't forget, these profilers slow down the byte-code
execution by about 30X, and so make any I/O look 1/30 smaller in
proportion than it actually is in an unprofiled, byte-compiling JVM (i.e.
"java -server").
