User Comments:
GUEST: Just working with 4 maven projects. Netbeans performance is terribly slow.I tried to improve it by setting GC options
-J-XX:+UseParallelGC -J-XX:+UseAdaptiveSizePolicy -J-XX:CompileThreshold=100 -J-Dsun.java2d.opengl=true

but the attempt has no result.
I think you have some architectural omission. For example, if I have maven pom project with about 100000 HTML resources (html, pictures, css, etc) , why you scanning these files continuously!?



Maximum slowness yet reported was 29238 ms, average is 29238

The JaaContextSupport.resolveContext() calls JavaSource.runWhenScanFinished() in EDT.
The JS.rWSF does parsing and should not be called in EDT.
