Hi,
For my lectures, I changed all fonts (lists, menus, code, ...) to ComicSansMS-17 Point-Bold. But, it leads to a slow-down of reactivity. I have to wait (about 2 seconds) when selecting/resizeing/moving windows or openning menus/windows (up to 10-12 seconds when openning a filelist!).
BTW, I'm using mac carbon VM 3.8.9b1 on a G4 1.33Mz powerbook 12" with 512M of RAM. I made the test with a full 3.8-6665 image and a basic one also.

Noury,

Try a 3.7 line VM and compare them (and let us know the result^^;)
As far as I heard, that is about the "correct" behavior of finalization in 3.8 VM and the "bug dependent" implementation in glyph caching of TrueType font.

Measuring 10Browsers, on Windows, going from default fonts to 17 point comic I got a ~37% slowdown on 3.8 and 3.9a-6681, and a 57% slowdown on 3.7.
I couldn't find any behavior as bad as what you saw. I did find a few bottlenecks that could be easily fixed and got scrolling about 60% faster, and brought the 10browser slowdown to about 26%.
Try out these changes and see if they help; if they are useful I'll submit them for 3.9.

I like the speed up, too :-) Go, Eddie! Karl
