I've found Ruby IO and database connectivity to be significantly
slower on Windows (identical and near-identical hardware) than on
Linux.  Even IRB takes a noticeably longer time to reach a usable
state.  A particularly nasty test is timing a script using ruby
-rprofile.  The profiling overhead seems to be much greater in
Windows, which points at some kind of underlying problem.
Sadly, I don't know enough about instrumenting compiled code to point
at the problem.
