Well, I just ran a very naive test and it suggests that zpt may be about
twice as slow as dtml.

I made a DTML Method, and a ZPT, identical to each other, containing
only HTML:

  <html> 
   Test
  </html>

Then I ran the ab benchmarking tool against each method, thus:

  # ab -n 500 http://localhost:8005/zpt_test/dtml

The results are reproduced below, along with the profiling information
(sorry if it wraps badly)
