we just started playing with ruby and ActiveRecord a few days ago at
my company and we're having major troubles of outputting xml fast
enough.
Pure xml output from ActiveRecord::Base takes approx 20s for 500
objects (that are small and simple). Does anyone have any pointers?
How fast is REXML?
Slow as hell. We just did a refactoring today, going from xml to json to pass AR data between apps. We achieved an order of magnitude speed increase and profiling showed 70% of the time on the client side was spent parsing xml and 30% on the server side creating the xml reppresentation.
If you're stuck with XML I'd look into a replacement for rexml.

The devil is in the details. I rewrote my XML-manipulation class to use
libxml instead of REXML and the libxml-based version of my routine takes
twice as long as the REXML-based version. So it all depends on exactly
what you do with it... m.
