For all intents and purposes, PerlEx is basically compatible with
mod_perl/Apache::Registry. However, the END {} blocks are interpreted
differently (augh!)... which shouldn't really be that much of an issue for
most programs.

The good thing about PerlEx as opposed to mod_perl/Win32 is that instead of
serializing all the calls to one Perl interpreter, ActiveState Perl actually
creates multiple Perl interpreter "objects" that can be round-robined among
the IIS threads.

I've been testing all my code on both PerlEx and mod_perl. And haven't had
very many problems at all with compatibility. I think UNIX/mod_perl is faster
than NT/IIS/PerlEx on the same hardware (from my unscientific observation),
but PerlEx seems much faster than ASPs.

Yes.

If you want Page scripting and the x platform (IIS) stuff, then you should
probably do the ASP side.

Without Apache::ASP as I understand it we cannot mix html/perl... is that
right? The Apache::Registry module allows us to speed up "cgi" processes,
but not page scripting per se?

Writing Apache::Registry and then moving to PerlEx will have greater performance
than writing Apache::ASP and moving to PerlScript Pages on IIS. However, the
performance difference is probably not that great compared to using CGI on both
platforms.

Win32/Linux cross dev... closing in :) Last comments?

Hiya :)

Thanks for all the help so far, it has proved VERY valuable.

We have narrowed our architecture down a lot over the last few days.

We will work with mod_perl/Apache/Apache::ASP under Linux. And we will use
Activestate's PerlScript under Win32. We will avoid as many "ASPisms" as we
can, and wrap the rest in a module for later changes if needed. Both systems
will talk to a MySQL or MS SQL dedicated box.

This SHOULD allow us a almost seemless ability to move between Linux/Apache
<-> Win32/IIS.

Has anyone actually used this sort of setup this way? Words of encouragement
or last minute red flags will be appreciated, we finalize on Friday :)
