Comment (by Premislaus):
My previous comment has introduced confusion. I'am sorry.
1. In gcc2h when you run GLTeapot, the system responds with a huge delay.
GUI draws slowly, you have to wait for the reactions of other programs.
2. In gcc4h is a little better. Something similar I observed when 4
GLTeapot is running.
In idle and do not demanding things is normally.
There is something wrong with the allocation of CPU time in Haiku. The
newly launched process, such as mount a partition, does not receive
priority. You have to wait until the system responds to the launch of a
program.
Along with this patch, GUI drawing is normal under heavy load (100% of CPU
usage). You can start at the same time 6 GLTeapot, song and video (frame
dropping). With this patch you have less waiting and I observe improve the
system responsiveness. I have a much better feeling, impression.
