As you are using Windows, mod_perl 1.x isn't really an option, as Windows
doesn't support forking (at least that's my understanding, I never tried
running Apache on Win)

So you should go with mod_perl 2.x

Sort of, but somebody with mod_perl 2 experience should be able to tell you
more on this issue.

Again, I'm running mod_perl on Linux, but it definitly is normal to get
quite a huge increase in memory usage. See
  http://perl.apache.org/docs/1.0/guide/performance.html
for more (mod_perl 1 related) info, or (mod_perl2):
  http://perl.apache.org/docs/2.0/user/performance/prevent.html

I'd second that ... The Win32 section of the mod_perl 1 docs
at http://perl.apache.org/ have a more detailed discussion
on what the limitations of mod_perl 1 on Win32 are. So
although mod_perl 2 isn't as mature as mod_perl 1, for many
people the benefits of mod_perl 2 (and Apache 2) on Win32
outweigh this disadvantage.

Note that, on Win32, mod_perl 2 requires perl-5.8.0 or
greater (ie, an ActivePerl build in the 8xx series).

There's a development release of libapreq2 available for use
with Apache/2 - see http://httpd.apache.org/apreq/. For
Win32 there's an associated ppm package at
http://theoryx5.uwinnipeg.ca/ppms/libapreq2.ppd. However, be
aware that this is a developer's release, and isn't yet
intended for production work.
