Quite right Spiral, I merely pointed out one of the reasons I would upgrade, quote" Of course there are more reasons for upgrading depending on your needs "unquote.
I actually run apache 2.xx on my local machine and tested every possible software, no problems, it just when it comes to production cPanel seem to be somehow slow like you said.
Apache 1.xx is less reliable on security than 2.xx, but >>"time it takes me to hack and / or crash sites running Apache 1.3.x is in a matter of mere seconds"<< is an over statement, don't forget there are patches in place besides all available security modules such as mod_security and all other measures outside of apache. Apache 2.xx would be the same if you leave your server on a vanilla basis as well.
