In my application I often return large amounts of data - for instance, a single user may have access to as many as 8500 accounts; each account may have several hundred detail records associated with it. I've solved my initial problem of being able to return thousands of records (for instance, I can return almost 48,000 detail records in a little under 5 seconds), but the problem I have now is that it takes FOREVER for the jsp to render. I mean, I've waited over an hour for this thing to complete. Does anyone have any tips on improving / optimizing the performance of a compiled JSP? I'm using Tomcat 5.0.18 Stable with J2SDK 1.4.1_02....
