A method, system, and computer program product for optimizing “Hypertext Preprocessor” (PHP) processes by identifying the PHP pages which are active on a server and forwarding requests for specific pages to a processor which has recently processed that page. A request processing optimization (RPO) utility assigns an initial request received at the server for a PHP page based on a number of factors which may include a relative usage level of a processor within a pool of available processors on a server. The RPO utility assigns a request to additional processors based on: (1) a threshold frequency of page requests; and (2) a resource intensive factor of a page request measured by average response time of the page request. The assignment of PHP pages to a particular processor(s) enhances cache performance since the requisite code for a specific PHP page is loaded into the processor's cache.
