I'm sorry to come late to this thread, but since my name has been invoked, I want to weigh in both as the author of the script (I believe that both scripts are now identical) and as a moderator.
I do think this thread has veered very far off-topic. Unless @Happi has specific questions, or anyone has specific feedback/suggestions for both QoS and SQM at the same time, let's end this thread. Thanks.
Update: I am invoking my moderator prerogative to close this topic. If @Happi has any further interest in this subject, I would encourage a new topic to start anew.
