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.

Noury,
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.
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.
