If you're using the Zend Accelerator, or PHPA from php-accelerator.co.uk, or APC from apc.communityconnect.com or bware from someone else (sorry, can't remember the URL) then the PHP process would only compile the first time and store the bytecode for execution on subsequent requests. 18 months ago, eweek did a ecommerce store benchmark comparison between CF, ASP, JSP and PHP. JSP, at the time, got 13 page requests per second. PHP had 47. PHP was NOT using any caching technology in that benchmark, but presumably JSP was. No doubt the JSP engine (Tomcat in that demo) has improved, but I would suggest PHP has improved as well. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
