If the driver is em for Intel Pro/1000 MT, that has received a serious boost. People are reporting close to light speed :-) Search for the thread "Performance degradation after upgrade". The devs have made networking for certain cards blazingly fast, its a ongoing process. So your comment might be way off. You need to test with -current if possible and then report back if gigabit voice/video perf is still bad even with your setup.
