2009 06/04/2009 03/31/2009 133 Caching is essentially a way of keeping the most used parts of a website in memory so that it gets served quickly. This will reduce CPU and I/O overhead and thus make the site very fast. Unfortunately this doesn't happen magically without some extra work. This talk will cover the several layers that you should know about how they improve the sites speed. Some of these will include: * "Squid":http://www.squid-cache.org/ / "mod_cache":http://httpd.apache.org/docs/2.2/caching.html (disk backed caching) * "memcached":http://www.danga.com/memcached/ * "APC":http://us.php.net/apc & other opcode caching * Application level caching * Configuring Apache properly * Solutions for python & ruby I will also go over how we utilize caching on the Drupal infrastructure which is hosted at the OSL along with other real world examples. 03/31/2009
