What would be Optimal Apache config for our box?

    Sorry if I am posting in the wrong thread but could not find an actual Apache forum.

    Since about 2 days we were under funny attack and our hosting company placed us behind TMS to fix the issue. But until they did that few of their admins messed up our Apache config and now we are left with lagging site , timeouts and all sorts of weird things.

    Our setup can be seen here

    and this is current Apache config

    fileetag: All
    keepalive: On
    keepalivetimeout: 7
    maxclients: 250
    maxkeepaliverequests: 150
    maxrequestsperchild: 1000
    maxspareservers: 50
    minspareservers: 50
    root_options: ExecCGI, FollowSymLinks, Includes, IncludesNOEXEC, Indexes, SymLinksIfOwnerMatch
    serverlimit: 256
    serversignature: Off
    servertokens: ProductOnly
    sslciphersuite: ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP
    startservers: 50
    timeout: 300
    traceenable: Off

    I still experience slow connection and first load is like a process is verifying something before it actually lets me in. But every 5-10 min the connection just dies for about 20-30 sec.

    please advise if this config is ok for our box.

    Thank you much!

    Hello :)

    You can browse to the following option to configure these values:

    "WHM Home » Service Configuration » Apache Configuration » Global Configuration"

    You may want to adjust the settings back to their default values if the firewall has stopped the attack in order to see if there is a positive change in the performance.

    Thank you.

    keepalive: On
    this set to Off

    timeout: 300
    this to 15-30 max

    and this
    startservers: 20
    maxspareservers: 10
    minspareservers: 30

    even assuming that you have high traffic (it will be forking processes automatically, when necessary)

    you got plenty of RAM, so even when you have many apache connections it might get stuck on database or something
    anyway, if its stuck on not enough apache processes, then its good to turn off keepalive or set it to 1s
