Use Loader1 to load all its own classes and those from Loader2
Use Loader2 to load all its own classes and those from Loader3

For the exact classloading setups I make Loader 1 import the module/packages exported by Loader2 etc.

I run the tests individually using e.g.
mvn install -Dtest=SiblingVFSImportPackageLoaderBenchmarkTestCase

Running each test individually, I get these average results over 7 runs

 || *Deploy (ms)* || *Load Classes (ms)* ||
| *Big ball of mud* | 1439 | 4485 |
| *Package* | 1321 | 4880 |
| *Module* | 1461 | 4874 |

The code lives in svn under  https://svn.jboss.org/repos/jbossas/projects/cl-benchmark/trunk https://svn.jboss.org/repos/jbossas/projects/cl-benchmark/trunk
