Profiler LOG

Dont know if it helps, but this is the profiler.

Netbeans freezes in fact everytime i run it, and it etas from 300 to 700 megs of memory and almost full CPU. I should make some screens of Activity monitor, and some from Netbeans GUI (when queue of actions contains for example 10 times "Deleting")

For me it looks like some unchatched loop, which tries to make everything more times than we want :D

I'm Running the same as creator of this bug.

Mac OS X 10.6.4, in x86_64 on MBP 13" 2010

Wish you nice day

Netbeans 6.9.1 profile

same problem, with 6.9.1 hogging cpu indefinitely with no user activity. The ol Parsing & Indexing Loop looks pretty busy.
Comment 4 Tomas Zezula 2010-11-05 13:13:59 UTC 
The parsing loop does single scheduled task which is the PHP (46.5s) and probably longer.
This task was schedules while you was still in the IDE as result of some action, but it takes long time.
The time is spent in php parsing and intensive queries (there is some IO and also class loading in order of seconds). The class loading is natural (the clases were not used before) the IO may benefit in the NB 7.0 from the memory caching integrated into jet-main e8f93be3c8c6
Comment 5 Ondrej Brejla 2012-02-14 12:53:13 UTC 
There is a lot of improvements in parsing in 7.2 dev. Can you test it there? [1] If the problem still remains, please, provide me some new profiling snapshot and reopen this issue. Thanks!
