Description luislobo 2015-10-20 16:40:18 UTC 
Since 8.1 RC 1, code formatting has become very slow. On 8.1 beta it was running fine.

This is for Node.js code.
Comment 1 luislobo 2015-10-20 16:41:10 UTC 
BTW, it happens randomly
Comment 2 Petr Pisl 2015-10-21 11:50:39 UTC 
I can not reproduce it. 

Could you provide a profiling snapshot?

Please reopen the bug, when the snapshot is attached. 
Thanks.

I've added a profiler. I cannot easily reproduce the issue, I hope this one helps.
Comment 5 Petr Pisl 2015-10-26 13:26:47 UTC 
According the snapshot, the formatting is waiting until structure scanner (navigator) finish its job.
Comment 6 Petr Pisl 2015-10-26 16:44:44 UTC 
Could you try to switch off navigator and try to reproduce it? Or could you provide me a file, where it can happen?

Another Profile. This time there was only Projects, and two js files open.
It took a while, then a "formatting please wait" dialog appeared. and finally formatted.

Now I'm using RC2

Comment 10 Petr Pisl 2015-12-28 14:59:52 UTC 
Is there a way, how can I reproduce it? Could you somehow share the project?

And If you switch off the navigator window, still happened?
Comment 11 Petr Hejl 2016-07-26 08:06:24 UTC 
I do not see any formatter code in the latest snapshot. It looks like lucene query is slow for some reason. The original call is coming from navigator.

Reporter, can you try the latest daily build? Would be great if you could provide a file or project for testing.
Comment 12 Petr Pisl 2016-08-01 12:58:14 UTC 
I have tried to improve performance of the method ModelUtils.findPrototypeChain, because last two snapshots the CPU spend here a lot of time.
