    Frequent High Server Load...what could be wrong here?

    I am wondering is there something wrong with the setup of my servers or is it really possible for a server with this configuration cannot cope with 1k+ daily uv?

    Server specs:
    Core2Quad 8300 @ 2.50GHz
    Speed: 1998.000 MHz
    Cache size: 2048 KB
    8GB RAM
    3x500GB HDD
    1Gbps port
    50Mbps Peak 300Mbps offpeak

    But, the server always experiencing high load. I have to restart apache to get it down but then it goes up again in a few hours. What can I do? Or is it the server admin to be blamed for?

    What is the best setup and if I were to hire someone to setup this server, who would you recommend?

    You've got to find the culprit process and you can do it yourself. Windows? Use task manager. Linux? Top and ps will point the problem.

    Server is linux.
    Site is mostly used for downloading.
    file sharing sites --> server --> users
    Daily users according to google analytic are 1000+ daily but site has limits of how many downloads server can handle (50 servers jobs at one time), downloads per IP (3/IP).

    I really need advice of how can I lessen the load issue. site is rsmaker.com.

    If its cpanel server then try to check the http process by using,

    #ps aux | grep httpd

    Actually, I would use ps -auxf and not grep httpd.

    Another thing to look at, is if PHP as a CGI you can see which script might be causing the problem, whereas with PHP as a module it makes it extremely difficult.

    Hi,

    When you said "high load" did you mean all the time? Server load is usually caused due the following Peak visitor times, log processing, database backup scripts, automated cron jobs etc. Could you please check these. Also make sure that any unwanted processes in the server are turned off.

    Some causes for High load:

    1, High server loads could be caused by just one or several resource-intensive application(s). Examples include very high-traffic Web sites, database-driven Web sites, forums, gaming sites, file download sites and so on.
    2, A high server load can also be caused by a malicious script or a "runaway script" which can continuously loop, dragging down the server 's resources.
    3, Too many websites on the one server - with the cumulative resources resulting in high server load.
    4, Running out of memory and swapping to the swap file.
    5, Server backups or server updates are taking place.
    6, Server comes under intermittent or continuous Internet attack.
    7, Mis-configured software causing errors.
    8, Users sending large mailing lists.
    9, Users/spammers sending spam email.
    10, Hardware issues including memory leak, bad hard drive, and network card.


    Please check them for a start.
    Cheers

    If it is serving only static pages, why apache ? You can go for smarter and faster web servers like lighttpd or nginx.

    As a short term solution, you may require to optimise apache ( MPM = Prefork , KeepAlive = Off and Timeout to be some 10 or 15 ) . Increase MaxClients / serverlit etc.. Does your site uses any databases ?

    I cant imagine high load from that many users unless its a database driven site and you do not have indexes on columns that should. Another possibility is it could have slow IO, maybe a bad drive or something. If its on *nix, use top and then hit "c" and it will show the full path of processes and you can usually quickly see if something is using most of the CPU and what it is.

    high load does not mean cpu load, it can be that the wait time from hdd is very high, that you can see with top against io.
    another try is system reporting and accounting tool "sar"

    It is NOT a warez file hosting. It is a rapidleech site.
    What is rapidleech? READ HERE

    What users downloading there are not endorsed by myself. I only provides a way for people who don't have premium accounts to download. I am kind of offended by your comment.

    Yes, it looks like but it is not a rapidshare interface, it has more than 50+ filehosts plugins in which people can download from them through the site.

    Back to topic, anyone can advise me about this issue? Thanks.
