The slow down is up to 10-20x. My implementation also does all of the events except SubtreeModified. The slowdown factor will depend on what mutations you are actually doing. I don't expect our implementation to slow down at all unless you are actually listening for the events. -- Stewart Brodie Software Engineer ANT Software Limited
