I am developing on Zend Framework2. Over the last few weeks the CPU reached %100 on every trivial task (even mouse point). I disabled almost all plugins but that was useless. I also tried to delete the cache. What helped at the end, was to put a filter on the TODO task list to ignore ZF2 library. Immediately the CPU went to sane levels and the IDE response was instant. ZF2 library size is 189M with git and has many @TODO I am working on: Intel I7, 120GB SSD, 8GB RAM with Fedora16 64bit Product Version: NetBeans IDE 7.1.1 (Build 201203012225) Java: 1.7.0_b147-icedtea; OpenJDK 64-Bit Server VM 22.0-b10 System: Linux version 3.3.6-3.fc16.x86_64 running on amd64; UTF-8; en_US (nb)
One more important note. The Tasks window was minimized in the IDE layout. I didn't really used it.
please attach the self-profiling snapshot taken during the duration of the problem - see http://wiki.netbeans.org/FaqProfileMeNow
Created attachment 119766 [details] Profile of class editing when there is no filter on the TODO tasks window
Created attachment 119767 [details] Profile of class editing when there is a filter on the TODO tasks window
As for your request I attached 2 files. I tried as much as possible to repeat the same routine in both profiles ( Editing class name and some functions delete )
Will look at it, thanks.
Seems to be a problem in the tasklist itself - there are many calls to TaskList.clear(), TaskList.fireTasksAdded() etc. Please evaluate, thanks.

Created attachment 119806 [details] Without filters on the tasks window - client 7.1.2 Edited a array. replaced variable and such
With the knowledge of the fix in 7.1.2 I went straight and installed the latest. While it seems there is a slight improvement, the performance where very poor. I edited an array with 20 elements and Netbeans paused for seconds (high CPU) when I edited or deleted empty spaces. This was resolved when I activated a filter on the tasks window that exclude the big library. I attached a new profile
