Currently I am running 6.32.2
I have long struggled with suspecting that queues in Mikrotik are slowing down my customers more than it should.
I thought I had solved the problem by going away from using the default-small queue type but I found the problem seems to be back.
Here is the scenario
PPPoE over VPLS tunnel running on MPLS over a reliable wireless link
PPPoE user has speed controlled by radius attribute
If I set the radius user to unlimited speed, I am able to reliably get 50+mbps
If I set the radius user to 40mbps download speed with default-small queue type I get max 30mbps
If I set the queue type to default I get max 37mbps
My Upload limit is 10mbps and works fine
I will continue to tweak my queue types in hopes to get this right but I am hoping someone else has found a reliable solution or queue size/type for high speed queues.
