A recently published redpaper draft titled WebSphere Business Integration V6 Performance Tuning provides some useful information for people wishing to set up, tune and configure WebSphere ESB, and WebSphere Process Server. It also documents some best practices for architecting your modules to gain maximum performance. These range from deciding how to get the right granularity for SCA components and modules, through to making judicious use of asynchronous versus synchronous invocations.
The paper is written by the WebSphere Process Server and WebSphere ESB performance test teams, including Paul, Sam and Rachel here in Hursley, so this is useful information straight from the people who know.
Talking of performance, we’ve been doing a lot of work recently on a couple of performance items for the next release of WebSphere ESB and the initial results look very promising.
