Linux Scheduler (opinions needed):

[A_Fradley]

I chose a degree project that requires me to modify the scheduler so that it is more efficiant when run on a standalone computer. However I don't know what peoples opinions are on what's good or bad about it as it stands and I thought I could get some opintions here. I'm going to base it on the latest version from Fedora Core. I chose the project from a list of projects offered by the lecturers at my uni thinking that modifying the kernal would help me learn how to make trainer programs for games and now it seems like it will be less to do with that. I'm still interested and I beleive I know enough about C/C++ to complete the project. (I'm expected to learn the rest as I go along.) I'm still new to linux though so I'm not sure what conditions the scheduler is good/bad at or if it's geared towards networks or what. So erm, apart from running lots of programs at once what slows linux down?

actually the thing that really slows down an os is when i switches between each processes, assuming that the process has been swapped out.

the other thing is process priority. if say an administrator is backing up the system, the backup process would probably be running at higher priority and therefore the other processes will be running slower.

hmm, i am not use rewriting the linux schedular is a good idea, it's quite complicated to schedule which tasks to run and stuff. anyway, good luck.
