In my experience win32 is par with linux generally with a few gotchas on
either side. Are your times with fsync=no? It's much harder to give
apples-apples comparison with fsync=on for various reasons.

Are you running stats_command_string=on? Try disabling and compare
results.
Is your loading app running locally or on the server?

I am very interesting in discovering sources of high cpu load problems
on win32. If you are still having problems could you get a gprof
profile together? There is a recent thread on win32-hackers discussing
how to do this.
