As a module, any misbehaving script is running within the same space as all the other scripts. If a script is able to knock out PHP (for any reason), all the script go. With CGI, they are run in separate spaces. No direct communication (unless the scripts are sharing memory by some way). If a script knocks out PHP, that script dies. Everything else keeps on going. The main downside to CGI (as I understand things), is that for each invocation of the script, PHP has to do the complete build up and tear down every single time. For every single script. With FastCGI, when the server starts, a pool of ready to go php instances are created. So a script is called, the build up part is already done. In terms of speed, I'd guess you'd have to be working pretty hard to see the difference between module/isapi and fast-cgi. -- Richard Quadling Twitter : EE : Zend @RQuadling : e-e.com/M_248814.html : bit.ly/9O8vFY -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
