There might be a difference with Win2003 running in VMWare and having
Win2003 running exclusively(not with VMWare) on the system.

There are reports that if you set Win2003 to optimize for
applications, instead of services, Firebird does run faster.
Apparently this is mainly due to the window that Firebird creates for
IPC communication and for the guardian to detect that the server is
running or not, and that maybe Win2003 recognizes Firebird more as an
application than a service, because of that window.

But, another factor that people don't realize(or forget sometimes) is
the anti-virus software that scans all files without exception.
