What are the reasons that PHP shouldnt be used in CGI mode? One is apparently the typical reasons of CGI having a lot of process over head due to process start and stop. Cant this be mitigated with fast cgi? Can we use PHP in fast cgi mode? If I were to use JVM based servlets or JSPs versus PHP, isnt it more efficient considering that PHP is interpreter based?

I am just exploring technologies, one question I had was, is PHP run as a ssi - within the process space of the webserver or is it run as CGI? If I can do both, then is there any support in PHP for Fast CGI? I read that session management is done by writing to secondary storage like /tmp of disks or databases, if I were to chose the Fast CGI option is there any in memory session management capability available?
