We're running 8 servers per core on 5450s. 64 forks per 2 socket server. 16GB is more than enough on Linux.
We've had an entirely server almost full, the CPUs are nearly maxed out but we didn't get any performance complaints. -----Original Message----- From: hlds_linux-boun...@list.valvesoftware.com [mailto:hlds_linux-boun...@list.valvesoftware.com] On Behalf Of Milton Ngan Sent: Thursday, October 22, 2009 10:39 AM To: Half-Life dedicated Linux server mailing list Subject: Re: [hlds_linux] L4D2 server requirements CPU shouldn't be much of an issue. Each game takes on average 10-15% of a core. There are obviously spikes that go higher. 8 player games don't actually take much more CPU than a 1 player game because the server is doing less AI work. On these servers, I have between 200-300 people playing at a time. This is very similar to the player numbers we see when running TF servers, except we run far fewer TF instances on the same hardware. Memory is still an important factor, because if you run out of RAM, then you will swap and your games will hitch due to I/O latency.

I find that I run out of CPU way before memory since the game is a CPU hog. Surely you can't run 50 servers with players in them all at the same time right? So how many can you run at the same time? How much cpu does a full 8 player server use? Thanks for your input. Milton Ngan wrote: > I can support 50 instances of L4D1 on a dual 2.5GHz Quad Core system.
