Friendster goes PHP: "Those of you asking why they switched from JSP have obviously never used Friendster, or any other JSP programmed site. They are almost always slow. I can't stand them. On the other hand, I've never been on a well-programmed PHP or Perl site that was unacceptably slow.

Of course, a lot of it is well-programmed vs. poorly programmed. But if they did a good job and implemented caching, then their new PHP site should be blazing fast for everybody. "
