I would understand if you would say that UDP sockets could be almost as fast as Unix domain sockets. But I never heard of TCP sockets being faster than Unix domain sockets. Every time I install MySQL on the same machine as the Web server, I disable networking to make it use Unix domain sockets, for either greater speed and security. -- Regards, Manuel Lemos PHP professionals looking for PHP jobs http://www.phpclasses.org/professionals/ PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/
