Routeros 6.9 - Simple queue problem

Hi, we´re using RouterOS 6.9 in the CCR 1016 12G.
When 700mbit Max Limit is set the target can not push more than 350mbit.
It’s without any parents and children, every simple queues is separatly, priority 8 as default and we have only 3 queues in this CCR.
I try all types of queue, but without success.
If we disable the simple queue for the client it works fine (but no limits).

Could anyone help please ?

Thank you.

Do you see dropped packets in the queue? If yes, how many of them in relation to those passed.

Yes, i can see dropped packets in queue:

37 dropped per second with traffic 57kpps .

(we have the same result even if the queue is enabled as unlimited !!! )


Thanks for any help.

Do you mean 57kbps (not kpps)?
That might be the problem. I don’t have a CCR, so can’t tell very much in regard, but I would suggest to use multi-queue-ethernet on the interfaces queues as first step. This type of queue is for multi-core routers like yours. Then try to increase the size of the type of the queue you are using on the simple queue. Lets say you are using default queue type the size of which is 15kbps. Increasing the size ensures that you don’t have dropped packets, but will increase latency.

I mean 57 kilo packets per second 57kpps.
We try all kind of queue, without success .

(we have the same result even if the queue is enabled as unlimited !!! )
someone else would say something about it?
