Re: [hlds_linux] srcds_linux multithreaded
I have been running one tf2 server through wine for the last 3 hours, and so far tickrate has never gone below 60 even on pl_goldrush and pl_frontier_final at 32 players. Metamod, Sourcemod, Stripper, TF2Items, SDK Hooks and CBaseServer plugins/extensions seem to be working fine. Both top and rcon stats report srcds.exe using up to 120% CPU The only problem so far, apart from the awkwardness of running the windows version of a program that has a native linux implementation, is that srcds.exe is using 3.2 GB of swap. I still have to investigate this, also because I have a total 2 GB of swap :) On Tue, Mar 15, 2011 at 2:48 PM, Claudio Beretta beretta.clau...@gmail.comwrote: TL;DR version: are there magic command line parameters or convars that enable multithreading for srcds games on linux?

Re: [hlds_linux] srcds_linux multithreaded
A few months ago there was a TF2 update that increased CPU usage significantly. The temporary workaround suggested by valve was to put -threads 3 in the commandline. I can't remember if it was a problem specific to windows or affected linux too, but from this we can say that -at least on windows- srcds has some sort of multithread support. And even in the (unlikely?) case that process explorer was wrong in reporting the CPU usage.. at the end the tickrate was stable at 66, which is the result I'm seeking to achieve on linux.

We did use CentOS for a very short time, it wasent the best(for us). We now are using fedora core for one machine (4 cores running 2 TF2+ 1 dods). Another machine with almost same spec. running Debian (2 dods) All is 32-slots minimum installs with custom kernels (no x-windows installed) We are monitoring all servers with munin and can se every stat in graphs. maybe you managed to get CentOS to run as it should, but we didnt. if you having problems do install debian on a spare hd and try ! we are using kernels from here http://www.ulrich-block.de Good luck !

I've come to the conclusion that srcds on linux can use at most one core. I hope I'm wrong, since it would mean I'm stuck at running 32 slots servers at tickrate 33 despite having good hardware. How you guys manage to run 32 slots srcds servers on linux?

Re: [hlds_linux] srcds_linux multithreaded
CentOS isn't too great for Gameserver hosting, or so I've found. I get much better throughput with Gentoo in comparison. Debian was much better then CentOS (There have been several notable performance increases with the latest Kernels, including 2.6.38 which just came out today). Realtime is retarded for GS hosting, especially when you're going for throughput. SRCDS is a whore, Valve doesn't seem to care at all which was made evident with the last wave of performance hurting updates. Their testing field is 32 players on CS:S, I'm unsure about other games. We're running dual X5650s ( http://ark.intel.com/Product.aspx?id=47922 ). Even this monster cannot handle 54 players that well. Kyle.

The same issue I'm experiencing when the server is full or something else? I'd rather avoid changing (again!) OS if it isn't really necessary, and I don't have a spare HDD to test it on :( On Tue, Mar 15, 2011 at 6:07 PM, Svensk Ljud Ljus Produktion i...@teaterljud.se wrote: Hi !
