Class::DBI is slow.  DBIx::Class is faster,  if you are looking for an
apples to apples test try using your hand optimized DBI in your model
instead of an ORM.  This will allow you to test Catalyst's speed instead of
Class::DBI.

ORM will always be slower on average than hand tuned SQL.


Your view looks like you are using your own TT/stash, Catalyst does this
with its default View:TT.  Also,  using tt, make sure you have compile
cache turned on and are using the compiled version of TT.

I do not see your other code that is 50x faster?  Are you using TT,
sessions what else is different?
