Description

« Hide

As soon as a tab becomes active with a JSP, my CPU pegs and idea just sits for like 30 seconds. If I switch to a different tab and back it's okay but the initial hit is huge. If I close the tab and re-open it the cpu thrashing starts all over.

Please, attach cpu dump.

From what I read in description this is normal. Upon opening any file (JSP included) background processing is started, which of course is CPU intensive. It shall be terminated on any user activity though.
On the other hand if you feel certain operation or analysis takes too much time please take a CPU snapshot and attach to the issue or upload to ftp://ftp.intellij.net/.uploads if too big for attachement.

Here is a cpu snapshot from me switching between two jsp windows (back and forth a couple of times). It seems faster than yesterday (I just started the project, and I only have one project open now) but the slow downs randomly crop up sometimes when I switch from tab to tab, open a new jsp or even just return to give the Idea window focus.

How many css files are in the project?

Try switch off 'illegal dependency' inspection

We have some sort of html help library that adds a ton of css files. The project has a total of 955 (basically one per help topic) css files. Turning off the 'illegal dependency' inspection seems to have gotten rid of the problem. I opened up jsps that had been problematic and they just open immediately, no lag and no cpu spiking. Thanks a lot for the help.
