Random stuttering + high pings - why?

8 posts in this topic


I'm running a nmrih server and experience some problems, i need some insight on what may be causing these problems.

Everything is setup and working fine the server is fast and has a quality network with ddos protection and all that other fancy stuff, yet at times i experience random stuttering and high pings! this mainly appears to be happening whenever zombies get spawned in later waves (not at the first few waves.)

Server type: Virtual machine (KVM)

Network speed:


OS: Debian 7.5 x64

RAM: 1024 MB

CPU: 3 cores clocked at around 2.x GHZ

Where it goes wrong:


Server's hardware utilization while this happens:


NMRiH server.cfg:

// 0 = Internet

// mapcycle_survival.txt - Survival maps only

// "Official" tags:
// custom - If your server is running custom gameplay settings/configs

// survival - If your server only cycles through survival maps

// 2 - Web server has the exact same "nmo_example.bsp" file located at "http://www.yourwebsite.com/nmrih/maps/nmo_example.bsp"

I joined this community as a last resort. I love NMRiH and that is why im trying to support it by running a stable and protected gameserver, but the kind of stuff that is happening as i described in my main post has an negative impact on the gameplay for everyone who joins my server.

People will leave because alot of random stuttering occurs and honestly, i do not blame them at all for that. its not cool and shouldnt be a thing.

What am I doing wrong?

SRCDS doesn't take advantage of multiple cores. Combined with your cores being clocked very low, this is probably the cause.
