ActiveState Perl very slow on IIS 6.0

We have moved to IIS 6.0 and suddenly some of our Perl scripts run very
slow. Database queries (Win32::ODBC) drop from "instantly" to four or
five seconds. We are using ActiveState Perl 5.8.4.810. It turned out
that the problem is related to Perl for ISAPI (perlis.dll). If we map
the Perl scripts to perl.exe, it runs as before and we have no delays.

Can anyone confirm that this problem exists? Is there a solution?

As long as running fine why worry right... but I can only let you know I run
ActiveState Perl in IIS 5.0 is seems fine to me.

I would worry because calling perl.exe for every hit to a .pl web page is
very inefficient and will become slow with even a moderate load.

I don't think it has anything to do with IIS since it does nothing for ODBC.
IIS is just executing Perl. Have you confirmed that this isn't a problem
with ActiveState Perl on IIS6 or maybe even ODBC?

There is one known issue with Jet/Access on Windows Server 2003 that was due
to a behavior change in COM+ -- that has a QFE. Not certain if it has any
applicability here
