PHP and JSP comparison

Has anyone done/seen any PHP-JSP comparisons, even ASP for that matter? I am really starting to like PHP and would like for my company to start using it as our active page alternative, however, I need help. Also, I know that milestones are close at hand for PHP 4 release dates, but are there any gu-estimates and will the direct Java support be ready? I ask about PHP 4 because for us to use it we need session and Java support. Lastly I know that JSP has some performance issues, but has anyone done any benchmarking with PHP 4? thanks, al *********************************** AL Lewis Systems Engineer Evolutionary Systems Inc. http://www.es-inc.com (831)392.1092 (831)392.1192 fax
