Cpu Usage

in Linux Server Support
i'm being told that 85% cpu usage is normal? can someone please clarify this... hopefully a dev that knows how the linux server runs. i would really like to get the cpu usage on my machine down (just having to upgrade the cpu is not what i want to hear) so that i can run this server. otherwise i'll have to remove NS i think because 85-93% cpu usage just isn't right. my other post is in the main server support forum but the only reply i got was to upgrade, so anyone that could help i would really appreciate it.

    Honestly you have the low end for servers now a days. Hell, even my server is about middle of the ground and it's an AMD 1900+; you shouldn't be concerned with 80-90% CPU usage.


    If you are running HLDS_L 3.1.1.0 and NS alone with no MetaMod, adminmod, AMX or Clanmod you can expect about 60% usage, of course it also matters what map you are running too. hera and bast are much better CPU then thier 1.04 counterparts but they still take more cycles then the other maps. Try running lost and see how your server runs, that maps seems to be very efficient.

    My specs are AMD 1900+, 512MB ram, RedHat 7.3 running 3.1.1.0, Metamod and AdminMod and about a dozen of so plugins between adminmod and metamod.

    Here's my server stats, CPU usage and such. I run a 12 player server

    I'm seeing 70% late game on a Dual Xeon 2.0ghz with 18 players on the server. (1 gig ram)

    I'm also running Admin Mod and Metamod.

    PS: OS is Red Hat 8.0 with latest SMP Kernel

    You all make me sick... I'm running NS on Redhat 9.0 with a PIII 600E WITH ping booster... Needless to say that when the server is full there it dosnt respond well to console input... *sigh*. Although, I don't have anything besides hlds_l running (outside what I need to keep the server talking to my NIC card).

    Just for comparison purposes here are my stats. I run a 2ghz 1gb RAM box on RH 8.0. Here is my stats:

    PID # 14447 - TFC Server, 14 of 18 players at the time of comparison.

    Your box would take up about 80% resources. 2GHZ box takes about 60% resources when it hits 14-18 players. 60% of an 2ghz box is 1.2 ghz. Your box might even be a little faster than mine.. <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->

    You could run a 20 player server because what I have found was after 14 players it kind of doesn't matter how many more players join the CPU doesnt go up by much. You could run about two CS servers if you'd like but whats two more CS servers to the community? Theres already an overwhelming amount of CS servers out there. I'd try NS until HL2 comes out and stuff <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->

    I don't know why your CPU usage is so high... My CPU usage is uber-low with 2.0 out and running HLDS 3.1.1.0. Here is my top with 21 out of 22 players on my NS2.0 server, on ns_tanith, 28:30 seconds into the game:

    This is actually higher than normal. Usually is at or below 25% CPU usage, commonly in the teens. There are also two counter-strike servers up with people on them, but they never use above 1% CPU.

    Someone logged off between the top and stat cut'n'paste. As you can see there are some thirty millisecond pings in there. I personally ping 20-30 on my server, and I have seen a ping as low as 13 in game. We run metamod with the configuration stored in a MySQL4 database... Lots of other **** run on the server too.

    For comparison, my system's hardware and software is as follows:

    Asus P4G8X Deluxe (7205 chipset - "Granite Bay")
    Pentium4 2.66Ghz
    1GB dual-channel CL2 ECC PC2100 RAM (2 x Kingston KVR266X72C2/512)
    Onboard BCM5702 Gigabit ASIC (using broadcom's driver, offloads most network/IP calculations to integated RISC processors)

    Gentoo Linux:
    cat /proc/version -> Linux version 2.4.20-gentoo-r2 (root@palace.clanhk.org) (gcc version 3.2.2) #1 Thu Mar 27 18:34:29 CST 2003
    All packages compiled with CFLAGS="-mcpu=pentium4 -O2 -pipe -msse -mmmx -mfpmath=sse"

    We used to run HLDS 3.1.1.1 for DoD, but after NS2.0 came out we got rid of 3.1.1.1 for 3.1.1.0. That improve performance by about 40% for us. Your CPU usage seems uncharacteristically high. Make sure you're running HLDS 3.1.1.0 If you don't have the low-latency pacth, preemptible kernel patch, and Igno's O(1) scheduler patched into your kernel consider adding those.

    I run linux server with latest HLDS revision on Athlon 1000, no admin mod, no metamod, CPU usage when full with 16 people is around 70-90%, runs nice but pings get a bit higher on some maps when full (bast, hera, tanith).

    The latest HLDS revision (3.1.1.1) is HORRRIBLE for CPU usage. 3.1.1.0 is so much better. You should consider regressing. 3.1.1.1 has serious problems.

    Private server is empty so its taking no CPU.

    I have seen the server get up to 85% CPU on maps like bast and tanith after hour long games. This is only a problem when the private server is being used also, because when it is full it tends to take 20-30% CPU and pings start spiking when both servers are trying to hog some CPU

    An official thread on this is now pinned at the top - if you find further tweaks to go with CPU usage, feel free to post in that thread (knowing that if it's just 'yeah, i agree' or 'NS sux0rs', it will get deleted). Thanks.

    As you can see, my server isn't vunerable. I also compiled the other exploit and tested it against my server and it failed to have any effect what so ever. You can use 3.1.1.0 without fear of security if you get the newest patch and maintain your system properly.

    Thanks ill switch it over to a different user.. The directory is actually from a regular user account but I wasn't sure how to start a process as a different user in /etc/rc.local (startup file). If you know how that would be great but for now ill start process up manually. Sometimes when I need to update my servers I kill the processes then do /etc/rc.local to start them back up. Its a Game Server only box. Thanks again for the heads up.

    Load average is the average number of processes in the running queue, IOW, processes whose state is "RUNNING", IOW, processes between which the CPU time is shared (i.e.processes that are idle or waiting for I/O don't affect it)

    82 MBit/s? That's just a tad big high there. With 22 players we pull about 400-500 Kbit/s to the server, and 600-700 Kbit/s out from the server (ie 1 to 1.2 MBit/s combined).

    15 servers? 15 game server processes you mean?

    I still don't believe you. Even if you had 15 30-player HLDS servers constantly full--which you don't have enough horsepower for even with hyper-threading--that would be less than 40Mbit/s combined up/down. Besides which, your response did nothing to answer the question of bandwidth usage for an NS2.0 server. That was the topic.
