Well not really; we know that we are running Tomcat, a web container which has its own (fixed) characteristics. It is a server side app which is processing non state based transactions which are thus highly like to involve a lot of objects being created and destroyed without too many hanging around for long; the details of the webapp, unless it is highly unusual, are likely not to matter particularly. This is a rule of thumb not an exact science and the vast majority of people who run Tomcat would benefit from running in such a configuration (or playing with it to see what the effects were) - read Sun's own tuning documentation and you will see the default settings are not said to be suitable for the majority of server apps. cheers Pete

I would argue any such rule of thumb is as likely to hurt performance as improve it for your specific app. Yoav Shapira Millennium ChemInformatics This e-mail, including any attachments, is a confidential business communication, and may contain information that is confidential, proprietary and/or privileged.
