    Question Server load over 20, is it that bad ?

    Hi,

    I have one dedicated server of mine who's load is constantly over 20. I know it is really high but my website is loading just fine.

    I have only 1 website running on this machine and I know it's taking lot of resources. I was wondering if I should switched server as the load is real high but on the other hand, it doesn't look like it affects the speed of my site.

    Is it bad for a server to have such load or is it fine if even at such load I find my things running smoothly.

    I'd really appreciate to have your though on this.

    Regards,

    G

    It sounds like the hardware might be getting close to the max. What does

    free
    uptime

    Say and that will give us a better idea of what is going on

    You;ve run out of swap space which is causing your issues. You want to get at least another 1-2GB RAM upgrade and that should really help

    Ok thanks.

    This is a cheap dedicated so I can't ask for RAM upgrade at this time (they don't offer it).

    However, beside moving elsewhere, is it that bad to have such load, could it break some hardware ?

    Try to optimze your web server (httpd) ... search in this forum for optimize apache

    Configure below paramenters in your httpd.conf:

    HostNameLookups Off
    ServerTokens Prod
    ServerSignature Off


    And provide below mentioned variable value from your httpd.conf fie:

    Timeout
    KeepAliveTimeout
    KeepAlive
    maxKeepAliveRequests
    MaxSpareServers
    StartServers
    MaxRequestsPerChild
    MaxClients
    MaxRequestsPerChild

    First settings were already matching (except ServerTokens, which I didn't find in my config file)


    Timeout 300
    KeepAlive On
    KeepAliveTimeout 15
    MaxKeepAliveRequests 100
    MinSpareServers 5
    MaxSpareServers 10
    StartServers 5
    MaxClients 300 (must be a high number, I get more than 150 connections at a time during peak hours)
    MaxRequestsPerChild 0

    Pretty unlikely.

    The suggestions to optimize things are good as are the suggestions to upgrade ram if at all possible, which sounds unlikely.

    If the load average isn't causing problems it is not cause for immediate alarm. In some circles it is quite normal to run machines that average a load of 10 ~ 15 at least. Not often in web hosting, but in many scientific and development environments that is quite the norm at times (albeit on much bigger iron).

    You don't mention what your hardware is doing exactly. If this is a download server or similar, another http server may prove more efficient. Check out lighthttpd and thttpd. Apache under most circumstances will spawn one process per download which won't be ended until the download is complete. This can quickly increase load avereages and decrease general server performance.
