Solving_the_C20K_problem_PHP_Performance_and_Scalability-phpquebec_2009
This document discusses solving the C20K problem of handling 20,000 simultaneous PHP users on a single database server. It describes how this can be achieved using built-in database mechanisms in PHP like database resident connection pooling, query change notification, client-side query result caching, scaling with stored procedures, and database partitioning. It provides examples of configuring and using these features. It also includes a case study and benchmarks showing how database resident connection pooling in PHP enabled a system to handle over 20,000 concurrent users.
