It's not even remotely true unless you're running PHP as a CGI and using some
particularly resource-intensive code. For reference, I have a development
system with a 500Mhz Athlon and 320MB. This is not a tuned system - somewhat
the opposite, in fact. I have code which queries MySQL to generate some XML and
then uses XSLT to turn it into HTML - this sustains somewhere around 45 hits /
second with 50 simultaneous clients; simple scripts hit ~155 hits / second.

If you were to create a tuned PHP build and run it with a tuned Apache / MySQL
using one of the script caches (Zend, APC, BWare) these numbers would go up
substantially.
