Ok, I tried without compiz and both Pharo and X11 using 16 bpp: It works better (still slow if compared to VW). For example: when pressing right button on the world, it takes almost a second for the popup menu to show up. Is that normal?

normally not

I didn't used it in another platform, I will try to give it a try under Windows to see if speed is the same.

Thanks

Is there a particular reason for Pharo not supporting 24bpp?

time and money.

I think all nvidia drivers for linux works up to 24bpp, but this depth is not listed in Pharo (using 16 bits looks a bit ugly)

normally displayScreen only supports ... 8, 16 or 32 bits

I found it really slow while using compiz at 24bpp, on top a of Gentoo 64 bit box (turion 2dual core 2Ghz).

I will use it now without compiz and let you know if it behaves better.

Do you have any performance test that I can run so that I have "numbers" to report? Because the slowness could be a subjective impression as I usually run VisualWorks.

Arturo told me that pharo was looking slow on his machine.

I'm using Pharo on Ubuntu 9.10 and experience no problem. Could you please try by turning off Compiz?
