+This project attempts to measure minimum overhead (minimum bootstrap cost) of PHP frameworks in the real world.

 * cost of template engine (HTML output)
 * cost of database manipulation
 * cost of debugging information
 
-Components like Template engine or ORM/Database library are out of scope in this project.
