You've mentioned that you also tried 2.5 and you don't see any difference there. I am very interrested to hear what version of 2.5 you tried. I am using 2.5.69 + some patches and it does not suck or behave brain dead like 2.4 does. For me I've quit with 2.4 from now on. 2.5 still has many things to do / to fix but 2.5 is _active_ developed and fixes _are_ going into 2.5 where 2.4 does not accept real bug fixes. If you want to give 2.5.69 a try, please apply the attached patch if you want to use it for your desktop. It gives you more interactivity. ciao, Marc --Boundary-00=_893z+nrFQrSWzXf Content-Type: text/x-diff; charset="iso-8859-15"; name="sched-interactivity.patch" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="sched-interactivity.patch" --- old/kernel/sched.c 2003-05-24 14:45:57.000000000 +0200 +++ 2.5-mcp/kernel/sched.c 2003-05-24 16:18:42.000000000 +0200 @@ -65,7 +65,7 @@ * they expire. */ #define MIN_TIMESLICE ( 10 * HZ / 1000) -#define MAX_TIMESLICE (200 * HZ / 1000) +#define MAX_TIMESLICE ( 10 * HZ / 1000) #define CHILD_PENALTY 50 #define PARENT_PENALTY 100 #define EXIT_WEIGHT 3 --Boundary-00=_893z+nrFQrSWzXf--
