Where's DBI? Did you sort this by wall time (-r flag)?
We are using Catalyst::Plugin::Cache::Memcached minimize hits to the
database. That is why you don't see DBI in there, but do see
Cache::Memcached.
Here is the output when I sort by wall time:

Lastly, Template seems to be taking up around 6%. I suppose I could try
caching template output, but that will take some doing, as every page on
our site can vary per user.
You can try my Template::Plugin::Cache module if you like. It caches
the output of included templates so you can cache parts of a page
instead of all of it. I have a patch from Peter Karman that makes it
play nicely with Catalyst's cache plugins. There are also some things
you can do to improve TT performance, which have been discussed before
here and on the TT list.

Yeah, we could definitely divide up our templates a bit better so that
we can utilize template caching on the static portions.
Thanks for the quick feedback Perrin!
