    HDD - 2x500GB SATA with RAID Level1

    and my Broadband Speed is 10-20 Mbps Conection.

    Software :

    Centos 5.5 x86_64
    Apache 2.2 , Mysql 5.x and ISPConfig3 , Pure-ftp, postfix etc..

    This is completely dedicated for webserver and i'ld like to tune Apache and Mysql to Handle more than 200k Pageviews per day.

    Take a look here:

    Also make sure that you install a PHP opcode cacher (eAccelerator, Xcache, or APC).

    To optimize MySQL, take a look here:

    Hi Falko,

    Thanks for your information and i've a small concern. How much Memory can we allocate to PHP Scripts (example i've total 16GB RAM and can i allocate 4GB RAM for PHP scripts and 2GB RAM for Mysql-server)?

    If we can do this can u please guide me how to?

    And is there any 1-click php scripts installer for ISPConfig3?

    AFAIK, there's no limit. You can set the PHP memory in your php.ini (I think it's /etc/php.ini on CentOS). Restart Apache afterwards.

    Unfortunately no.
