Webapp debugging slow

Hi, we are very happy with our new IDEA licences. But we would appreciate if webapp debugging would speed up in the near future. The first time a JSP is accessed it needs a lot of time to load. Subsequent requests are handled considerably faster. Our app contains framesets which loads several JSPs a time which needs of course even more time.

I observed that JSPs are compiled every time the webapp is restarted. Is that necessary? I am sure some percentage come from the unnecessary recompilation.

Webapp debugging is one of the few moments I wish JBuilder back. JB Prof. couldn't even debug JSP. But actually I am not very often interested in debugging JSPs because they contain (and should so) very little code. But JSPs are part of the webapp ...

Jetbrains, can there be something done about it?

Hi Michael,

Let's separate the issues:
1. The JSP loading and compilation are handled by the app server, thus the
performance of these operations depends only on the server being used, not
IDEA.
2. As of keeping compiled JSP code feature, you are welcome to submit an
SCR.

Hi Eugene,

Thanks for the reply. What I tried to explain is that the recompilation is one but not the only one (and IMO not the most significant) reason for the loading time. When starting the webapp without debugging the JSP are also recompiled and nevertheless the webapp starts quite fast. The JSP recompilation is the only evident fact for me - therefore I mentioned it. My hope is there are other (non-appserver-) reasons you can something do about. What do you mean?

Well, certain job is done in order to parse generated files and store line
number mappings.
Then I need some measurements: what you consider "fast" and what is
considered "slow".

Thanks for your interest.
Our start frameset which consists of 4 JSPs needs 10 seconds (fast) to load in non-debug mode and 45 seconds (slow) in debug-mode. I've got a 1,8 GHz Athlon with 512 MB RAM and run Win NT 4.

Ok, I have added an SCR for this issue:
http://www.intellij.net/tracker/idea/viewSCR?publicId=7558
We'll investigate the behaviour. Any additional information about the
problem is welcome to be attached/posted in this SCR's thread.
