GlassFish partner Caucho is featured in this blog comparing performance of Drupal (the popular content management platform) running on Apache 2+PHP and Caucho's Quercus (100% Java implementation of PHP5+extensions). Scripting on the JVM can offer load-balancing and clustering technologies (courtesy of GlassFish for instance) but it can also let you use the world of enterprise Java APIs. Here it seems to also demonstrate how Java's HotSpot JVM adaptive optimizations kick-in and provide better performance than "native" interpreters on a real-world application.

These tests were conducted all without caching enabled. Interestingly enough, comments suggest using Terracotta (another GlassFish partner) and EHCache, used by Greg Luck in the Wotif.com architecture.

See this post by Ludo to get the Quercus interpreter running on GlassFish.

In the ever-growing list of GlassFish partners at CommunityOne (May 7th, less than 2 weeks away!), here is Caucho. Caucho's Quercus is a fast, 100% Java implementation of the PHP language allowing developers to use PHP flexibility for the web interface and Java for stability.

As previously highlighted by Ludo, Quercus works just fine on GlassFish v2 which opens the door for PHP developers to APIs such as JAX-WS/WSIT or JPA, to the EJB3 component model, and to GlassFish features such as load-balancing, administration, or clustering. Caucho will be at GlassFish Day to show exactly this: typical PHP applications running on a complete open source Java stack.
