I have a test tariff (internet) configured for 10Mb download & 5Mb upload using simple queueing (no contention) on a PPPoE setup with a MikroTik NAS.
I can confirm the simple queue is pushed to the MikroTik and I see limits are correct, however, the speed tests do not reflect the package. In fact, I am receiving quite a big disparity in my upload and download. I receive 1Mb download and 200Mb + upload on all tests.
I can confirm IP Fast Path is not configured on the MikroTik NAS. Please see image of queue attached below:
