The main difference is that PerlRun compiles your script every time and
clears out globals in the current namespace every time.

That's very low. Why did you do that? Were you having problems with
higher numbers?
I use Apache::SizeLimit and set MaxRequestsPerChild to 0 (unlimited).

Using a global for that is not such a good idea. Any value you put in
there will persist between requests. That is one common source of this
sort of "caching" complaint. The other is accidentally creating
closures. Look for situations where you do something like this:
my $foo = 7;
sub bar {
print $foo;
}
That will cache the value of $foo between requests.

Make sure you aren't opening a database connection during server
startup. Throw in a log statement where you connect to the database and
make sure it doesn't happen before you send in a request.
That's all I have time for now. Hope that helps a little.
