    Hi,

    I saw many posts from google regarding to this question, but there
    were no definite answers..

    some say, it's mod_ssl, some say it's mod_perl, some say it is mm. But
    my case, it just doesn't make much sence to me at all.

    Here are the 2 test machines that I have, both have the exact same configuration

    A is a lot more powerful than B

    machine A, p4 3.0 2GB Mem
    machine B, p2 450Mhz 128MB Mem

    Both have mod_php, mod_ssl, and no traffic has been sent.

    Looking at the httpd sizes, I start to wonder ... How come Machine B
    only uses around 15Mb per httpd, while machine A takes 155Mb, and
    while they have exactly the same software, same configuration.

    Can somebody please tell me why this is happening? What did I do wrong?

    machine A:
