Solving the C20K problem: PHP Performance and Scalability

A summary of my talk at PHP Quebec @ http://conf.phpquebec.com

PHP is widely adopted for database-backed RIA.

• PHP lacks true connection pool; can a commodity database server sustain 20000 concurrent users?
• How to ensure availability in the face of a database server failure?
  
• When it comes to scalability, more PHP code or more frameworks (i.e., classes) translates to more CPU power; how to simplify PHP programming and reduce the amount of PHP code using built-in Oracle database 11g mechanisms?

The Community Connect case study will be discussed.
