| |
i have written a kernel patch for (more or less) public access machines (in my case : web servers, some with telnet access). the problems i have are : - people can run any number of processes, and this way make everything slow. - if a few programms are doing heavy i/o traffic, all other programs suffer.
not all problems are solved now, but i can do at least a bit: for example, i can give some amount of time to a user - if he has several processes, each process less time, so they get all together the same time a normal process would get.
i don't understand the whole memory management in linux now, so that part will change (my current changes will not hurt you, but they are not as effective as i hoped).
the patch is 25k, so i don't want to post it here. it's available at ftp.inka.de/sites/dungeon/kernel
i would realy like to get some opinions. i know that some parts are dirty hacks, so if you have an idea how to write this in a clean way ...
thanks.
andreas
