I would be tempted to say, back out all your changes and return to a stock configuration, except for the net.inet.ip.ifq.maxlen parameter. I posted in early august that I was able to push nearly full gigabit speeds with a Dell R200 w/4GB of RAM with a pretty stock configuration. Eventually I had to bump maxlen and the state table but that's about it. I don't see these problems on an mid August snapshot. I haven't had a chance to try the latest ones yet though. --- James A.
