One way to work this out is to use a webserver that is fully
multithreaded, with pooled connections to the database that can be
shared among threads as needed. This yields much superior performance
and saves a ton of resources.
One example of such type of webserver that has been fully multithreaded
and under heavy use since 1995, and has a PHP4 module is AOLserver, that
powers mighty aol.com and digitalcity.com (with mere 32 K hits per
second).
AOLserver also has a built-in database abstraction layer and Tcl
interpreter (with the option of caching compiled code of scripts), and a
comprehensive API for building massively scalable dynamic websites.
