I haven't tried mos on pup for a long time (and even longer since i used 3.9), and i can't remember how frogger behaved, but maybe the additional 68k was welcome in that case, even though context switches cripple that kind of parallelism.
I don't think i understand what you're saying here.
BTW, i also can't check on powerup hardware right now, and results will probably differ, but i just checked a 320x240 mpeg file with both frogger and mplayer, and guess what, frogger eats 25% CPU while MPlayer eats 16% on my pegasos2 G4 (probably more recent libavcodec, a bit more optimized).
I believe you, but this is certainly not the case on PPC Amigas, where MPlayer is much, much slower than Frogger. Ask any MOS-PUP user and he will confirm this. :-) Perhaps MPlayer uses Altivec??
In any case, as you said, ambient and mui are irrelevant, as they just idle 99.9% of the time when unused.
That's right.
About Ambient, the fact that it uses MUI adds some slight overhead. However, workbench is certainly NOT much faster. As a quick test, just try and display 1000 files in ambient and workbench, in icon and list mode, and see who wins.
Not a very realistic example, imho. :-D I can't find a directory in my partitions with 1000 files. It's bad for the FS.
Anyway, Ambient should be faster in some cases, but i insist that WorkBench feels faster in everyday usage.
