Using 7.2 RC1 with line wrap (word-style), trying to add a new item to the top ("Record your changes in the trunk here.") of the file mentioned in the URL is painfully slow - the IDE freezes for several seconds after typing each letter. JDK 7, Ubuntu.
Reproducible. Seems to be again issue with Navigator window (as in issue #209413). Try to close it, it helped me and IDE became much faster Product Version: NetBeans IDE 7.2 (Build 201207160020) Java: 1.7.0_05; Java HotSpot(TM) 64-Bit Server VM 23.1-b03 System: Linux version 3.5.0-4-generic running on amd64; UTF-8; en_US (nb)
Changing priority to P2 because it happens in relatively small JS file ([1], ~200 lines) as well and makes Navigator window basically unusable. Considering future 7.3 release, this should be priority. Symptoms are the same as in issue #209413.

Created attachment 123195 [details] profiler snapshot Here's another profiler snapshot but in this case Navigator (and also DOM Tree) window were closed. There was a significant delay between pressing key on keyboard and IDE showing it in editor
Created attachment 123196 [details] sample file for the snapshot above
Vlado, I'm confused - is the issue about html editing with linewrap enabled or about some navigator (html? js?) issues?
I'm sorry for the delay, I missed the last comment. First, it seems to me it is a lot better now (at least with HTML, JavaScript file still has the same problem as in issue 209413). I don't think it's related to line wrapping (it's hard to tell now when it seems fast but I believe it also wasn't related to it at the time I reproduced it) but to the Navigator window. If Navigator is closed, the IDE responsiveness is fine no matter what line wrap settings you have. Jesse added exception report about high CPU usage which I can confirm (closing/opening Navigator doesn't make any noticeable difference and IDE didn't not freeze) and closing file or project as such didn't decreased the CPU usage. I added some slowness reports but nothing crucial (once it happened after I clicked on some item in Navigator while it was fully populated) Product Version: NetBeans IDE Dev (Build 201209120001) Java: 1.7.0_07; Java HotSpot(TM) Client VM 23.3-b01 System: Linux version 3.2.0-30-generic-pae running on i386; UTF-8; en_US (nb)
The Jesse's report http://statistics.netbeans.org/exceptions/exception.do?id=610784 fixed by: changeset: 232573:67699e883d4b summary: removing amusing code causing heavy performance problems Based on latest Vlada's finding I'm closing the issue as fixed. Please file an issue against javascript if the perf. problem persist there.
