HI Mike, just for the record though, this problem with simple queues happens on everything I have used, for example we have a number of 2011's out there and simple queues drop packets and start queuing packets well before they fill up, I just observed one queuing and dropping packets on a 10M queue when the traffic was at 1M, then at 4M, it dropped them like hot potatoes, it causes all sorts of problems with VOIP too. This router has a custom queue type setup for the queues, it's a PFIFO type with a 200 packet queue, it shouldn't drop a packet unless that queue is flat out. I think it's more noticeable on the CCR's or higher speed queues more than lower speed ones as it's just almost impossible to get anywhere close to the high speeds before the queue drops it's backside out. Perhaps I might try the RC version on this 2011, I am cautious though with the amount of bugs MT seem to be introducing lately.

In case you missed it, latest version of 6.19 includes fixes explicitly designed to address general queue problems with CCR models: NOTE: in this build we applied a patch that should solve most of the queueing related performance issues on CCR. If these changes will provide positive feedback we will consider to put them into release of 6.19. Please, test queues on CCR and report results and any problems you might find. It also brings improvements for long term stability of the CCR. They consider this a very important update, and so are also seeking feedback where possible - good AND bad! ;-) Cheers, Mike. _______________________________________________ Public mailing list Public@talk.mikrotik.com.au http://talk.mikrotik.com.au/mailman/listinfo/public_talk.mikrotik.com.au
