jamie zyskowski resolved BEEHIVE-106:
-------------------------------------
Resolution: Fixed
i've updated the control scenarios to use the
@Threading(ThreadingPolicy.MULTI_THREADED) and added a new control/scenario
pair that uses a control with SINGLE_THREADED. With the latter, their is
significant overhead compared to the former. I'll look into this and open a new
issue if required.
> Controls Perf Regression: 3X increase in scenario times

> description:
> The regression seems to have been introduced somewhere between rev76140 and
> rev109265. It occurs standalone and in a jpf/tomcat env. There are two
> scenarios that show the regression. The first uses a custom control that has
> one method which takes a string and returns the length of the string
> [StrlenPgmTest]. The second takes a variable number of integer args and
> returns the sum of their values [VarargsPgmTest]. Interestingly, a third
> scenario that takes an integer and returns a string of the int size does NOT
> show this regression [VarretPgmTest].
> steps to repro (standalone for simplicity):
> cd $BEEHVIE_HOME/controls/test/perf
> ant rebuild
> cd bin
> . ./perf.sh StrlenPgmTest
> expected result (within 20% of this time value):
> TEST: org.apache.beehive.controls.perf.standalone.StrlenPgmTest
> hash=-1989672960
> time=4026
> actual result:
> TEST: org.apache.beehive.controls.perf.standalone.StrlenPgmTest
> hash=-1989672960
> time=13938
