Hi
I help develop an email website (http://www.fastmail.fm) and recently we
wanted to move over to providing proper timezone support for users (eg give
us a location, and we'll keep the time up to date, rather than having to
change for daylight savings every 6 months). As part of this, we were goi

This is why I think the biggest win for memory would be having XS based
time zones. This would also help speed somewhat, but I think the memory
savings could be very, very substantial.
If you look at the compiled Olson DB bits used by libc, they're fairly
small binary files (<1-2k usually).
You're not somehow accidentally pulling some other bunch of modules in are
you? Have you tried dumping the loaded modules in each case with something
like:
print Dumper([ sort keys %INC ]);
And comparing them? What you're seeing definitely sounds weird, it offhand
it sounds like something els
