How fast is MorphOS?

[Dan]

How fast is the 68k emulation in MorphOS compared to a 060-50Mhz?
UAE on my PC is 6 times faster than my A1200 060-50Mhz, I clocked it when decoding jpgs in Collector, is Pegasos/MorphOS faster than that?
How about the PPC JIT for MorphOS?

[Dan]

I would expect MorphOS with JIT to be faster than this, definitely.  Btw exactly how did you do the test? I could do it, but I'm not sure  what you mean. Decoding a single jpeg doesn't take enough time to  clock it.. I'm not familiar with Collector, maybe there's some batch  mode that you used. I could try it if you'd like some hard figures.

It´s a thumbnail program so I made a index from a directory with  33 jpgfiles. Also note that it is made for 256 color screens it´s only half speed at 24bit screens. The libaries it uses to decode jpg is available for ppc, i think.


Since the 600Mhz G3 is half the speed of UAEJIT then the G4 1GHz will be the same speed as UAEJIT?
When will MorphOS get JIT?

>Since the 600Mhz G3 is half the speed of UAEJIT then the G4 1GHz will be the same speed as UAEJIT?

   Question makes no sense The G3 can not be "half speed of UAE JIT" because any speed difference obviously depends on the PC you throw at it, not just UAE's JIT: A G3-based Pegasos without JIT may very well be much faster than UAE/JIT. And vice versa. Faster or slower is very much a matter of Ghz. Also, please keep in mind that we are talking about how fast classic m68k code is executed, ie. "old software". This thread is not about the speed of the G3 but about the speed of the emulator. That said, some comments on speed:

Sorry, what I meant was that Morphos without JIT is equal in speed to UAE with JIT on a MHz for Mhz basis, meaning that a 1Ghz Pegasos would be as fast as my  1Ghz PC?

Ok, if boot time  is included a pegasos will always be faster than a pc.  And with the morphos-jit things will get even faster. Then there is also the silence of the Pegasos. I´m almost convinced to buy a pegasos but does my favorite programs work?
I know PPaint and Photogenics works but does DPaint and PerfectPaint work?
And what about Visage, DiamondBOX and Collector ?
And ArtPRO ?

[Dan]

Thanks Madgun.

Visage: Yes. (Kinda slow though. The included MysticView is much faster.)

Is it slow when opening the screen or loading the picture?
I run it from DOpus like this: "path/Visage wbmonitor {O}" to stop it from opening a new srceen evertime.
Anyway MysticView is Morphos native right? because its slow on a 060 an even on my uae.

Sorry, I should have elaborated a little more. Opening the window is quick enough.. .

 :-?
Window???
Visage  always opens its own screen to display the pictures!
And there is an option to disable the internal 68k assembler optomized jpg loader and use datatypes instead but I haven´t bothered with it yet.

[Dan]

visage can use datatypes by specifying the -datatype option on the commandline.    May as well use multiview if you want it in a window though.

Thats what I don´t understand, what WINDOW is he talking about
Doesn´t MorphOS allow the programs to open their own screens?

[Dan]

Thanks for clearing that up Kronos.
I want to buy a Pegasos but which one should I get the Peg1 G4 or the Peg2 G4?

[Dan]

Sorry I didn´t saw that.
