Description mclaborn 2014-04-29 14:50:51 UTC 
Product Version = NetBeans IDE 8.0 (Build 201403101706)
Operating System = Linux version 3.2.0-61-generic running on amd64
Java; VM; Vendor = 1.7.0_51
Runtime = Java HotSpot(TM) 64-Bit Server VM 24.51-b03

The compile-on-save function seems slow in generating class files.

By examining the time stamps on the source and the generated class files, I'm seeing a 6 second delay between the save of the source file and the class files.

The file in question (OrderPost.java) is 6800 lines of source code, and generates 22 class files (the main and 22 inner classes). There are numerous references to other classes, both in the same and in other NB projects.

6 seconds seems to be slow for a compile of this size.  

My computer is 8 cores of "Intel(R) Core(TM) i7 CPU Q 820 @ 1.73GHz".

It certainly feels slower than it was in NB 7.

what really performing anything is the EditorParsingLoop thread.
Comment 4 Tomas Zezula 2014-05-17 16:14:35 UTC 
The CoS is blocked by Java Overridden annotations.

@Tomas: Any news here? It is annoying and lowers my productivity. I always have to try 3 times and wonder if the class is already compiled or not.
Comment 6 mclaborn 2014-06-12 14:23:43 UTC 
Strongly agree with markiewb - productivity is much lowered.

It's not caused by this issue. Please create a new issue on Maven, the Maven has to wait unless for CoS before it executes the project.
This issue causing that the CoS execution takes longer time than it's needed.

This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.

Thanks for your cooperation,
