Performance Tools APC Boost lighttpd Memcache nginx Pressﬂow Squid Varnish

“Do not hack core!” -d.o #144376

Unless...

...it’s REALLY worth it! “Pressﬂow is a distribution of Drupal with integrated performance, scalability, availability, and testing enhancements.”

Pressflow If you want performance, don’t think twice! API-compatible MySQL-specific Reverse proxy support Backport new Drupal enhancements More cutting edge https://wiki.fourkitchens.com/display/PF/Comparison+-+Pressflow+versus+Drupal

lighttpd & nginx Alternative web servers FastCGI Lightweight compared to Limited module support Apache Serve static ﬁles quickly High-extreme gain, Integrate with Boost complicated setup Load balance atop Apache

APC (Alternative PHP Cache) Opcode cache Shares PHP memory between processes Will be built-in to PHP6 http://php.net/apc Low-moderate gain, dead-simple conﬁguration http://www.ﬂickr.com/photos/jtyerse/208109946/

Boost Saves Drupal output as files Work with lighttpd or nginx http://drupal.org/project/ boost High anonymous gain, simple-hard configuration http://www.flickr.com/photos/kgelster/2779025573/

Memcache Made up of 3-4 components Pool memory resources over a network Moves DB cache to fast memory http://drupal.org/project/ memcache Moderate gain for both authenticated and anonymous users, simple-moderate conﬁguration http://www.ﬂickr.com/photos/kgrocki/4476048611/

Varnish Requires Pressﬂow Handle 3k-7k req/sec Page cache in memory, separate from Drupal http://drupal.org/project/ varnish Extreme performance for both anonymous and authenticated users, very complicated setup

Panetheon Formerly Project Mercury Drupal Performance-in-a- box Includes Varnish, APC, Memcached, Solr, and others http://groups.drupal.org/ pantheon
