I'm not aware of any such plugin, but it seems that sort of plugin would be 
"fraught with peril".  Keeping timing  results comparable from one run to the 
next require lots of attention to repeatability in the execution environment.  
Tests probably would have to run on the same machine on both tests, with the 
same load on the machine, and the same tasks running on the machine.  Even 
then, I would still expect variation  between test runs.

When we tried measuring performance like that in our environment, we eventually 
loosened the "failure thresholds" so much that the tests were no longer really 
telling us anything about performance.

If you really have repeatable test runs and repeatable results, you could 
consider storing your test results in a file and could compare the results from 
a JUnit style test, failing the JUnit test if the values were "out of bounds".  
The Git publisher plugin or similar might then help you push your results to 
your source control system.
