The petunia website has been updated with benchmarks from a recent version. Also, it is claimed that "This version is already converted to AmigaOS4, and running on the native PowerPC system".

| AmigaOS4 Petunia benchmarks : Comment 3 of 80 | ANN.lu |
| Posted by Neko on 18-Aug-2003 09:56 GMT | What's the point? Running 1.3
julia_fpu crashes HARD by accessing a strange memory location.
I couldn't get Mandel to output any times or frames values? It draws fast
enough, though, but what's the story with this 500x200 window? Are we living
in the dark ages of 2:1 aspect screenmodes? :)
c2ptest also outputs nothing in terms of benchmarks.
Demoeffect doesn't draw anything (contrary to "a bubbling picture effect (pixel displacement) on a 320x240 CGX screen from Stephen Fellner") and gives
a HIGHLY different result depending on what the phase of the moon is that
day. Maximum was 235.73, minimum I got was 148.94, and sometimes it would get
192.75 +- 2.0 fps more often than not.
Whatever happens, they only draw for a second anyway, which is a stupid way
to test the speed. Why not run it for 4 seconds and take the 2nd and 3rd second
as an average of the real speed? Then your graphics card doesn't factor into
it and it's an ultimate test of the EMULATION, and not how fast your video card
can fiddle with it's RAMDAC.
Atop that, they are all more tests of how fast WriteChunkyPixels is, and not
anything else. It would have been better to use, perhaps, WritePixelArray()
which would stress memory out during frames, stress the emulation out for the
calculations, and finally and simply do ONE OS call to display, instead of
calling redundant functions.
One of the easiest optimisations to make in a program is not to call functions
more than you have to. The calling conventions of most operating systems take
time!
I still say something like RC5-64 would be a better test of the emulation, or
something that is entirely CPU-bound, and then we can compare it with a more
complex test like graphics or sound or whatever.
