Is a note I posted a while back on pbForth speed. It really is very fast - not
as quick as legOS, but fast enough for what we're doing.
In fact, NQC and native firmware is fast enough - we just don't have enough
variables....
As a point of interest, I think that the Saturn V attitude adjustment
on the rocket bells is 20 times a second.

| (...) This is correct. (...) Hehe :) Yes, this is correct. LegOS is also faster for some other reasons- it samples the sensors at a much faster rate than the standard firmware, so legOS programs can react much more quickly than standard bytecode (...) (24 years ago, 6-Oct-00, to lugnet.robotics)
