- Some figures are not available when the underlying framework does not allow the feature. For the ext: ones, that can be due to pending work (AOP alliance interfaces can emulate a before advice just as it is the case in JBoss AOP).
- after throwing advice appears to be slow since it first, is an overhead in throwing the exception (user code) and second, in catching the exception and do an instanceof to check the exception type (advice code).
- latest run: Dec 20, 2004, as per Spring Framework team feedback.
AWbench is a micro benchmark suite, which aims at staying simple. The test application is very simple, and AWbench is mainly the glue around the test application that applies one or more very simple advice / interceptor of the framework of your choice.
