An analysis of TWiki performance following computer simulation of overuse

The web collaboration platform TWiki (TWiki.org) was installed at CERN by IT-PS following a request for a Wiki from group of software developers. Since then, TWiki has grown in popularity and today the statistics (Jones, 2008) shows more than 4000 registered editors and over 40000 topics. In order to guarantee acceptable performance for the future, a risk assessment would help to identify any bottlenecks that the system may come across. In particular, it may prove difficult for the current file system to cope with the increasing number of topics. Simulating future use can help forecast when such difficulties would arise.
