Hi, thanks for your feedback, never run the server as root so I never noticed this *weird* behaviour :S This specific unprivileged user (/*not root*/) I'm doing the tests with is allowed to set realtime scheduler for its own processes.
Kernel is: 2.6.32-279.9.1.el6.x86_64 (official binary shipped by centos) What I can't understand is why srcds_linux tries to do such change on its own... If I wanted to see it make use of realtime scheduler I would do that when starting... I do not like processes doing things by their own :S Additionally this kind of behaviour would make people run the gameservers as root because it will magically performs "better" thanks to the automatic scheduler changes :O Are we opening a Pandora's box? :D PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 13660 testtf2 -3 0 288m 174m 19m S 9.6 1.5 0:10.58 srcds_linux 13653 testtf2 20 0 103m 1568 1224 S 0.0 0.0 0:00.00 srcds_run pid 13660's current scheduling policy: SCHED_RR pid 13660's current scheduling priority: 2 pid 13653's current scheduling policy: SCHED_OTHER pid 13653's current scheduling priority: 0 let me see what happens when running as root :) Il 29/09/2012 18:35, Ulrich Block ha scritto: > Am 29.09.2012 18:30, schrieb Marco Padovan: >> Hi, thanks for your reply. >> >> In my case it is not srcds_run doing that, it's srcds_linux that does >> something. >> >> "priority" changes a few seconds after srcds_linux has started (right >> after "create 4 threads" gets printed into the console log). >> >> In my case it's changing its own scheduling parameters moving from the >> SCHED_OTHER into SCHED_RR. > > Which kernel are you using?
