Reuqest object with so much data

Hi All,

I would like to ask whether a request object with so much data and getting that data from request object in JSP is a heavy process? If yes then which one will take less time. Using request object or using scriplets and call java methods from JSP? I know writing java stuff in JSP is not a good design but this application is quite old and we are not allowed to change anything . We are trying to make Minor changes to improve the performance.

Any such changes will have no impact on performance.

Thanks Bear, But can you please guide me what are the steps we should take to improve the performance we are also using Hibernate to fetch the data from DB.

Guessing won't do anyone any good. Get a profiling tool (no, I don't have a recommendation -- do some searching) and find out where the problems really are. Doing things like "maybe it'll be better if I use scriptlets" will not get you anywhere. Find out where the real problems are and then fix them.

P.S. 9 times out of 10, the database and queries run against it are the biggest performance hog in a web app.
 
It is sorta covered in the JavaRanch Style Guide.
