Will our own local adjustments affect/conflict with the release 3.4.0x?

<http://www.usit.uio.no/it/rt/modifications.html> We're dependent on a
stable release in production. What kind of speed problems are other
universities dealing with?

We haven't had any technical problems running Apache 2.x and mod_perl
1.99.x, although Best Bractical strongly recommends Apache 1.3.x. We are a
bit worried if there are some speed problems due to the Apache versions we
are running, and something to do with the warnings BP has issued in their
install-readme file.
