Using a web accelerator in eXo Platform

Some students at IFI (a partner university in Hanoi) completed a research project on reducing access time to static content served by eXo Platform. Their attention turned to Varnish for the power of its configuration language (called VCL). It allowed them to fix typical issues in web acceleration (such as “cache-control” HTTP header or cookies) without having to patch the source code.

They produced some wiki documentation there. A performance gain of 10 was observed during their tests.

Direct access (average time) Accelerated access (average time) Number of served objects
26.88s 2.79s 104

This technique only applies for public static pages served by eXo products. Also please note that the eXo WCM team has some plans to deliver a more fine-grained and integrated cache module in a near future.
