Although the original test was in Windows XP on a single processor box, the
final tests that all passed were on Windows 2000 Server running on a Dual
PIII 933MHz box with 1Gb of RAM. The motherboard is an MSI Pro 694D.

Has anyone done any tests comparing PostgreSQL on Win32 and *NIX
platforms on
same/similar hardware ?

I suspect that the initial connect could be slower on Win32 due to
reported slowness of
fork() there, but are there other issues ?
