A factor of 2 is good :) For my document, hanging punctuation slows
down things a LOT (from 10 sec for three runs, to 60 secs for three
runs). What I usually do is to use no protrusion for test runs, and
add protrusion when I really have to make the final document. This can
be done easily using something like

\startmode[final]
\usetypescript[serif][hanging][normal]
\stopmode

\usetypescript[mainface][texnansi]

\doifmode{final}{\setupalign   [hanging]}

Then add --mode=final flag to texexec when I want protrusion.
