Tsung is an easy to use open-source multi-protocol distributed load testing tool. The more simple way to use it to stress test your machine would be using pgfouine to setup a test from postgresql logs: http://tsung.erlang-projects.org/ http://pgfouine.projects.postgresql.org/tsung.html Tsung will easily simulate a lot (more than 1000) of concurrent users playing your custom defined load scenario. Then it will give you some plots to analyze results, for disk io though you'll have to use some other tool(s) while tests are running. Regards, -- Dimitri Fontaine http://www.dalibo.com/
