Advantages of using Passenger + Apache over Webrick

I want to convince my management that using Apache + passenger setup is way to go on production rather than having webric开发者_Python百科k or mongrel

I have found some points from the net.

It would be great help if you could add your thoughts as that will defiantly help me to present my points. (technical details are welcome)

and It will great if you could send some links if you have any

thanks in advance

cheers
