!! JUnit Test Performance

Going from JSPWiki 2.8 to 3.0 I noticed a dramatic increase in time it takes to run the JUnit tests.
\\All tests were run on an Asus laptop with 1 GB memory and an Intel Core Duo 1800 MHz processor.

||Env.||Tweak||Total time
|JSPWiki-2.8| none|5 min. ?
|JSPWiki-3.0 |none|15 minutes 11 seconds
|JSPWiki-3.0 |JUnit task attribute forkmode="once" in build.xml|8 minutes 3 seconds
|JSPWiki-3.0 |LoggerFactory  c_isLog4jPresent = false (no JMX Logger Objects)|?
