#98586 - Yes, the things posted apply in this cas
Responding to: Jan Waclawek's previous message
Still looks useless?
Yes, the things posted apply in this case as well. Using the example you give, someone using a cycle counter and C makjes the routine just squeeze into the allotted time. Now two years later someone, for valid reasons, optimize for size (which usually makes code slower) and BOOM. Also, it is not uncommon that a new release of a compiler is slower in a few places due to code changes that makes it more efficient in many other places.
