Yeah, that is pretty odd. I have a customized galaxy.c (from xlock) that really pushes X (on my machine anyway) to it's limit. I was getting really choppy performance with more than 1200 stars- but once I compiled X with egcs it smoothed right up. Could I have possibly un-jammed something in a config file somewhere? I didn't change anything else except to rebuild, and the difference was considerable. It's not an objective thing, but I would say that my xlock mode ran ~15% faster after the compile, and I was able to go up to 1600 stars before seeing choppiness. I was just messing around- I'm a dabbler. The reason I'm asking, is I'd like to squeeze as much performance as possible out of this box, and this could prove to be a learning experience. I'd like to know why it improved so much?? Maybe I could twiddle it a bit more and get 2000 stars...
