This post is the first one of a series about scaling out WordPress.

Goals

The purpose of this series of posts can be summarized as followed:

• Experiment the different bricks (load-balancer haproxy, mysql replica, session sharing)
• What kind of performance increase we can expect ? Is the performance increase linear with the number of web fronts?
• What will be the bottlenecks ?
• What kind of tools can we easily use to stress the application ?
• What kind of tools can we easily use to measure the performance metrics  ?

Plan

Performance Measures

• CPU and RAM influence on the fronts
• APC influence of the fronts
• CPU Generation influence
• Cache influence
• Number of fronts influence
• Using Graphite

to come :
Sessions sharing
