One more to add:
~21ms Pd-0.39-2 vanilla
The difference between 0.39.2 vanilla and extended is probably due to
the improvements in Tcl/Tk. vanilla uses 8.4.5, extended 8.4.14
+cvs. For Mac people, Daniel Steffen recently has done a lot of work
on making Tk run faster on Mac OS X in 8.5, so if anyone wants to
experiment, I think there could be some real improvements there.
Thanks all for the responses, I am also hoping to get some tests of
the most recent Pd-0.40.3-extended nightly builds that use polygons
instead of lines for the boxes. I am hoping to track down the
mentioned slowness.
