[PD] why do [bp~] and [vcf~] sound different?

For rough benchmarking dsp objects, I generally just put what I'd like to test
into an abstraction, then I create a lot of copies and watch the load meter
accessible through the Pd menu. It's a bit crude, but quick to do.

For benchmarking message based objects I use [cputime]: Again make an
abstraction that e.g. receives a bang on a global receiver to start the
calculation. Then use a triple-trigger:

 [start benchmark(
 [t b b b]
 |   |   |
 |   |   [s reset_cputime]
 |   [s benchmark]
 [s get_cputime]

 [s reset_cputime]
 |       [s get_cputime]
 |       |
