Using JProbe, I noticed that my application was repeatedly compiling the same JudoScript scripts. I added a cache for compiled JudoScript scripts which reduced the calls to ParserHelper.parse():

RunCallsCumulative TimeCumulative Objects PercentCumulative Objects
11,3005.5%13.6%1,116,603
2130.3%0.3%23,456

Not a bad first optimization for our first use of the JProbe profiler.
