JSP Page loading..

There are many things you can do

1) Implement paging/ pagination so that only a range of records are retrieved, so you can break 6000 to say some 500 records per page.

2) Optimize your SQL query, see if it is obtaining a cartisian product - cartisian sets take a very long time - simplify the JOINS.

3) Pre-compile your JSP pages with JSPC.

4) White-space compress the output

5) Remove unwanted code, optimize your java/jsp code

What tool are you looking for?

If you want to use the Jasper compiler you can call it from your Ant build script, here are the details on how to invoke it from Ant:

http://tomcat.apache.org/tomcat-5.5-doc/jasper-howto.html

It modifies your web.xml, and creates a mapping of each compiled JSP class file, so make a back-up of your existing web.xml

Also you can use this Firefox extension - Load Time Analyzer:

https://addons.mozilla.org/firefox/3371/ to measure the overall page performance.

If you want to white-space compress your files, you can use Ant's Replace Regular Expression task : http://ant.apache.org/manual/OptionalTasks/replaceregexp.html to find and replace extra white spaces with a single white space but you'll have to watch for certain things like open comments // otherwise it can break your application.
