I discovered a rather significant performance issue in Equinox regions that can severely impact the performance of service and bundle event firing when there are many listeners registered with the framework. https://bugs.eclipse.org/bugs/show_bug.cgi?id=476074 https://bugs.eclipse.org/bugs/show_bug.cgi?id=476145 I mention this here because I noticed a few jiras being worked that relate to subsystems performance. If folks are using aries subsystems and have a system that contains lots of blueprint or DS components then you have a system with a lot of service listeners. You may want to pick up the latest equinox regions once the fixes are available to have better performance.
