Tomcat 4.0.6 Solaris 8 Java SDK 1.4.2 We have a web app that is slightly slow. This is a problem because it is just a bit slower than the app it is supposed to replace. This has the customer upset, partially because we all hate change, but also understandably, the customer wants it faster. We had a third party build the application but we will maintain it. For whatever reason the company that built it will not be providing any more support as to how we can make it go faster.
We have looked at the box, and it does not seem to be taxed. We have tried setting CATALINA_OPTS to maximize performance but tomcat does not seem to be using the additional memory and the system's load average remains low. Is there any way we can have tomcat use more resources, as much as necessary to run the application faster? On a side note I can find no documentation that explains the difference between JAVA_OPTS and CATALINA_OPTS? Also, we tried upgrading to 4.1.24 yesterday on another test server. The application will not run correctly on the newer version of tomcat, any ideas why? The results of the queries are not correct and the data is not returned correctly. Is there any major change in tomcat 4.1.24 from 4.0.6 that would cause such a disparity. Thanks, -Mark
