Run, do not walk away from cfForums. It is a curse. It's one of the most
poorly written applications I've seen. I've read every single line of
code, and my god, it's junk. We had over 30 forums and it was slow and
unresponsive. Not to mention debugging the application and/or
integrating it is a feat in patience. The code is so disorganized and
backasswards.

Actually - if I remember correctly - CF Forums was never encrypted. So
no matter what version you have you should be able to dig in.
My main issue with it is that the fundamental codebase for CF Forums was
begun with CF 2.0 and was maintained on a "oh, do we HAVE to!" budget
and timeline. It was a fine piece of software 5 or six years ago, but
it's age is just too apparent now.

Yes, maybe, and yes. :)
If you are talking about rewriting it I assume you have the open
source version. CF Forums main bottleneck is that it uses subqueries
to generate the message counts. Get a lot of messages, or a lot of
forums and it starts to blow a gasket. It's also been a while and
there may be a new version out...so my experience may be outdated
here.
The key optimizations that needs to be done it start precalculating
those topic totals, etc, remove all the looped over queries, then
start in caching.
In the end I was able to get a forum with 50! forums and over 75,000
messages displaying in sub 100ms times with a single user, before
any db optimizations. Under load it did well...can't remember times
though.
