Subject Re: Suggestions for performance improvement

Hi Rahul,
One issue is that your GroovyStatic test is mixing statically compiled and
non-statically compiled clases.  I changed the GroovyPlain classes to be
compiled statically, and the results went from

                             user  system      cpu     real

JApplication.java             433       0      433      433
JApplication.groovy           646       0      646      655
Application.java           963173   18907   982080  1131540
Application.javaStatic     750500      14   750514   853262
Application.groovy        2541527      41  2541568  2607827
Application.groovyStatic  2006609      30  2006639  2049778

to

                             user  system      cpu     real

JApplication.java             411       0      411      411
JApplication.groovy           561       0      561      585
Application.java          1021404      21  1021425  1097055
Application.javaStatic     759105      15   759120   826062
Application.groovy         922849      17   922866  1088130
Application.groovyStatic   762211       3   762214   822157

I experienced the Gradle issue as well.  I'm too tired to think right now
if there's a workaround, but in the mean time GMavenPlus works just fine.
