Catalyst would likely speed things way up for any users still running mod_cgi, and would likely have speed benefits for hose running mod_perl. Probably the biggest speed benefit of the framework is that it consolodates all the database handling. My understanding of DBIx::Class is that it is really fast when compared to standard DBI. Max might have more to say on that though.

In my experience with NHibernate, it is often faster than hand written 
query based apps. This is because it caches things heavily and batches 
writes to the database. Properly configured it also almost universally 
uses proper indexes too. I assume DBIx::Class would do the same thing 
(memcached support, flush buffers, ...). The point being that, sure you 
could optimize a single query to be be faster, but that isn't the proper 
optimization point most of the time (it is at the 
batches-of-queries-level to reduce db roundtrips).
