Databases (be oracle, mysql or other) are another stories and many of them are faster. However one does not have to run php in 64bit mode to talk to database servers running in 64bit mode. That being said, the main issues are not only for php but many libraries used by php. They did not support windows 64bit very well and they have not been tested enough to be ran on production servers safely (by all means). -- Pierre @pierrejoye | http://blog.thepimp.net | http://www.libgd.org -- PHP Windows Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
