not too impressed with this article.. When was client side javascript a server side performance bottleneck? On the contrary farm out as much work as possible on the client instead of doing it at the server, like sorting tables and stuff. Things like javascript tabs are also worth lot in terms of performance, serve one page that contains the content of 10 pages = less requests to the server. eAccelerator = old skool, why not APC which is the php opcode cache favoured by Rasmus Lerdorf? Why no advice on using a cache in apache or in front of apache to serve static stuff directly from memory?
