The issue is that the per call time seems a bit high on some of these.  Granted, I've got a lot more TAL statements in my page templates than I would like (eventually I will pull these out into scripts), but are these numbers unusually high?

It all depends how complex you page templates are.

You need to find the slow/complicated bits and make them faster, if 
you're experiencing slow page load.
