Running 2 Dedicated Servers Using 2 Ports

LockNLoaded

<div class="IPBDescription">= LAG?</div> hi.

any experience server ops here/ or perhaps Monse? can answer this quick question. <b>Does running NS, over the same IP but different ports effectively influence performance/lag on each other?</b>
i.e server1 12.34.56.78:27015
server2 12.34.56.78:27016

Need a formal answer and explanation if it does and why so i can forward them to the server gurus on my side. thanks!

I'm assuming that since the ips are the same, you are running 2 servers on one machine? If so, the server specs should be substantially high, as one NS server = 3 CS servers (approximately). NS is a major cpu hog (at least, until 1.1 comes out).

verbose

Running two instances of HLDS on the same IP address will have no measurable impact on performance. Nor will two IP addresses, or even two NICs. The problem will be as Duck suggested; right now, the CPU requirements of NS are steep, so it'd take a beefy machine to run multiple servers, preferably a multi-proc system.

thx all for the prompt and straight forward replies. yes, its ONE machine, 2 servers on the same IP but opposite ports. Each 16-Player, and it tends to lag as the game starts to entend past the 30 min mark, or theres too many structures around. sometimes, this happens even when the other server is empty and i have no choice but to change the level to another (pings start to rise past the 200 mark, when at the start its below 100 for everyone).

any suggestions?

there's really nothing you can do except run the entity stripper and renice both processes to like -15 . But even that won't help a whole lot.

Remember that even an empty server does take up a chunk of cpu time. So the ability to run a 24 player server does not mean you can successfully run two 12 player servers with the same performance.
