Bad performance and memory problem with 4.5.4

Hi all,
I have a struts/web application with 800 classes and 150 jsps. IDEA 4.5.4 is very slow and the memory always grows.
Which tool can I use "inside" IDEA in order to sent the problem to JB guys?

P.S.: I don't know if it is the correct forum. If not, which is the correct forum?
