Is it possible to achieve minimum latency with Qos on Mikrotik?

Question

Mikrotik

Good afternoon.
Configured Qos for clients and for traffic type (SIP from ports 5060 10000-20000 and RDP from port 3389).
I set a 5Mbit limit for clients, and 1Mbit for SIP ... but it doesn't matter.
The speed limit works. SIP always gets its own speed, no matter how busy the channel is.
The question is, is it possible to set the minimum delay for certain traffic using Qos on Mikrotik? If it detects packets that fall under some rule, does it immediately stop processing all other packets and "skip" the necessary packets forward?
Now it turns out that if I load the channel using iperf and work in parallel via RDP, there are delays. They are smaller than if I just turned off QOS, but still felt.

Answer 1

Mikrotik has queues where you can prioritize traffic.

Answer 2

If I understand correctly, in the existing rules you need to check the passthrough box so that the packet processing is not interrupted

Answer 3

Look in the direction of the queues' prority parameter. 1 - highest importance, 8 - will be processed after all others.

Answer 4

And just take a Mikrotik with a more powerful processor
