I have never benchmarked it, but I do run pg on Cygwin/Win2K/XP and
Slackware Linux 8 on the same laptop. PostgreSQL always *seems* slower under
Cygwin.

However, I know that one of the guys at Greatbridge did do some benchmarking
and as I recall reported getting comparable performance up to about 100
users.

It's possible that it's because you are running on Windows 98. For the 7.2
release we've done all regression testing on XP/2K - I suspect that Jason
only tested 7.1 on NT4 or 2K.

Who is this guy ? What I can do to get more preformance ?
Is't possible to compile 7.2 sources under Cygwin ? Do I need to do
something special ?

Sounds like the answer is "stop using Windows 98".

Now that Dave mentions it, I do recall that it was Great Bridge's
people who had gotten pretty much the same numbers from their TPC-C
benchmark on Cygwin as on Linux.  I'm quite sure they'd have been
using a current-at-the-time Windows ... so, either NT or W2K.
Probably NT but I can't say that for certain.
