Try running the Cygwin version with more that 65 connections.
Try running the Cygwin version doing more than 10,000 transactions over
5 connections (50,000 transactions). Now run a vacuum.
Try running the Cygwin version doing more than 10,000 transactions over
5 connections (50,000 transactions), run
an application that during that test will turn a tif into a postscript
file for 5 different people and then load it into the
database....

Cygwin is fine if you want MS Access level performance (O.k. that is a
little harsh but close).
Cyrgin is not fine if you want Linux/FreeBSD or any semblance thereof
performance.

It is slower on rights, connection startup, limited on connections,
tcp/ip transfer and you should
never run PostgreSQL with sync off unless you are not worried about data
integrity.

I disagree... read the other posts. CreateProcess does not scale like
CreateThread.

I don't know that 320 hours would deliver a threaded port but I also
don't want to go at this
the wrong way.
