Easier: optimized php.ini for responsetime?

Okay, my last question was a little.. weird. New one: Can you tell me optimized php.ini settings for faster responsetime/loading of a page, on a not-so-fast pc and a not-so-fast connection? The implicit output_buffering = ? zlib.output_compression = ? more?? Gzip uses more cpu than zlib, cause gzip waits for the whole page and zlib does parralel compressing, thus slower/longer waiting on a page to display. ob_start(""); or better ob_start("ob_gzhandler"); ? Am i wrong in these statements i make here? Please, additions for improvements! Marvin Vek
