Scalability & Performances

XWiki is written in Java/Java EE. As such it scales as well as Java scales.

Virtual wikis

As an example XWiki's wiki farm currently has 10000+ wikis created (running on 2 clustered JVMs). This is using the unique Virtual wiki feature of XWiki (This is the ability to have several wikis running on a single JVM).

See the tutorial on how to set up a Virtual XWiki environment to learn more.

Clustering

XWiki provides an easy way to setup clustered instances of XWiki based on network events distribution.

See Clustering for more details.
