I've been reading about the memcached and Xdebug and Zend_Cache. I've got lots to learn, but it is exactly the type of material i was trying to find. I am not currently running an opcode cache. I may be doing "premature optimization", but i want to design the entire system intelligently from the get go rather than having to rebuild later. you know 'work smarter not harder'.... Is it possible to run xdebug on a virtual host server on which i do not have shell access? I can modify php.ini via cgi, but I don't know if i'd be able to view the results of xdebug on the machine. Your opinion would be appreciated. Thanks so much, i feel like i've just been shown a whole new world. dK `
