This is excellent work, thanks for doing it!
One unexpected observation:
06-circle-alpha with colorkey+RLEACCEL is incredibly fast compared to
05-circle-noalpha, I wouldn't have expected that. Can anyone explain
why this might be so? Was that actually blitting anything visible?
Actually

One thing to note: I think RLEACCEL is highly dependent on the content
of the image, and the name implies run-length encoding which implies
that images with large areas that are the same color would benefit most.
I think it would be useful to run these tests

I have no idea what happened here. I sent a follow-up email to try to
rephrase, but it hasn't gone through yet. Maybe it needs to be
moderated; it's 107 KB. I've decided to take the attachments

Hi
always label the axis in a graph!
So what does the x-axis mean? And what the y-axis?
Thanks for the tests.
Sorry, the x-axis is which image it was. Each bar is a different kind
of treatment of the image. The y-axis is time

Could you post the images you use as well?
Thanks for a great report!

So convert_alpha() is a huge win, and RLEACCEL is some icing on the

Great work, thanks!
1) Can I see the code?
2) What about convert() -- this

Huh?
Can you rephrase that?

Just for grins I did some benchmarking on using convert_alpha() and
RLEACCEL. These are blitting a 32bpp 70x70 surface with per pixel
alpha on a 2GHz MacBook pro with pygame 1.7 and SDL 1.2.11.
I used the python timeit module, and blitted the image 100k times on
an 800x600 32bpp SW screen
