How fast is MorphOS?

@Dietmar:

Dear lord. And then to think we once thought the A3000 to be the hottest thing since sliced bread... How did we ever manage with those machines?

I think that GoldED, like any other event-driven program, spends most of its time waiting for user input rather than in OS-functions. I also think that much of speed gain you feel is simply the fact of having a 600 MHz CPU at your disposal, with a flat Amiga-like memory space. (I'm not sure though, the feature list of MorphOS is inconclusive as to what kind of virtual memory/memory protection it offers. Can some kind soul please explain?) But it's definitely nice to see that old programs just breeze along. Now hope and pray that once people start developing seriously, and taking advantage of CPU speed, programs continues to breeze ;-).

Well, that's the not-yet-included VM subsystem---what does MorphOS do currently? Is it flat, or paged? Or perhaps a combination? (While it's too bad that there isn't any more information available, I respect that decision. There has been too much flaming going on regarding VM on the Amiga anyway.)

@Dietmar:

Yes, of course, that's the challenge of an editor: do as much as possible in as little time as you can. But as I understood the original statement is that it was claimed---or at least hinted at---that the efficiency of the OS (functions) was the root cause for GoldED's speed. While in fact it is simply the 600 MHz of computing power, as you so clearly explained. I must say that what you wrote down surprised me: a 600 MHz CPU not yet fast enough for an editor...? Wow. You did a helluva job on the original then, which ran very well on my A4000. Then again, I suspect the program has evolved considerably since I last used it.
