Re: [hlds_linux] Fun with linux kernel configs
I looked into it: calling gettimeofday() in recent glibc versions uses the kernel's vgettimeofday() call, and thus isn't really a problem. See my other email about sleep() usage though. - Neph On Tue, May 20, 2008 at 1:20 AM, Thomas Hjorth [EMAIL PROTECTED] wrote: On Mon, 2008-05-19 at 19:02 -0700, Nephyrin Zey wrote: calling gettimeofday() is somewhat sickening - I might try and put together a plugin that re-implements it in userland via a timer and re-routes the call.

[hlds_linux] Fun with linux kernel configs
I've been periodically switching up my linux kernel config in an attempt to figure out what our friendly srcds software enjoys, and recently ran into something fun with this config: 2.6.25.4-rt1 kernel (realtime patchset), full RT-mode with all the fun RCU options on, non-tickless, 1000hz and all fun RTC options on What happens is srcds_i486 uses 0-10% CPU when loaded up with 32 players. It was using 80-95% previously. The catch is 'sirq-timer/0' and 'sirq-timer/1' (for each cpu) bloats up to ~70% cpu usage.
