do anybody have a good idea how to measure speed.
i know you can get Hatari to do a profile, but i think, that i am not smarting enough to do that


the situations is this, the original road routine is first clearing the left side of the road, print left, right side of the road and then filling it, then its clearing the right side.
if no road is present at that line then it clear the whole line.
(its doing all about on all 4 bp)
i have found that the road is not printed on bp3,bp4 , so i use the blitter to clear bp3, bp4 on the whole bottom array, so now i only have to clear bp1 and bp2 left and right, and print the road, on either bp1 or bp2. (use the blitter on all about)
but i have been thinking of just clear the whole button array (all 4 bp) using movem.l
when i can save a lot of test and loop for all the clear routine and all the init of the blitter, up to 3 times on every line,
but i will clear one bp more that is necessary but only where the road is. so my question is, is it faster, i think it could be but it would be nice to know for sure.
I welcome all idea and inputs
