Gilles Guirand wrote a series of articles (in french) about cache management and eZ Publish performance published in phpSolutions. The first article « Cache mechanism, templates and INI » has just been made publicly available (Creative commons) and is now available in english on the eZ sharing platform share.ez.no
A big thank you to Samuel Bouic for the english translation of the articles written in french for the phpSolution magazine.
Ez Publish performance
EZ Publish is a flexible and powerful CMS that currently powers a large variety of websites with low and high trafic.
This power comes at a price : The general resources consuption, SQL resources in particular, as well as disk I/O
All those mechanisms have to be controled to size its architecture and to fully understand the impact of a parameter, a cache-block directive or even the massive removal of cache (templates, cache-block or view cache compilation). The publication follows the same timeline as in phpSolution, separated in 4 chapters covering everything you need to know about low-level eZ Publish cache management.
