How to properly increase the priority of ICMP packets in Mikrotik?

Question

Mikrotik

Greetings!
I want to increase the priority for all ICMP packets on Mikrotik. I did it like this:
1. Mark ICMP packets incoming, outgoing and passing:

/ip firewall mangle
add action=mark-packet chain=input new-packet-mark=pktICMP protocol=icmp
add action=mark-packet chain=output new-packet-mark=pktICMP protocol=icmp
add action=mark-packet chain=forward new-packet-mark=pktICMP protocol=icmp

2. Increase priority in Queue Tree

/queue tree
add name=Prio1 packet-mark=pktICMP parent=global priority=1 queue=default

The Bytes and Packets counters go up and Queued Bytes and Queued Packets show 0. Is the
solution correct? Is it possible to improve? How to do it through Simple queues?

Answer 1

You must set the rate limit: limit-at=15M/15M max-limit=100M/100M
Otherwise, queues simply won't work.
And it will work if your interface is really loaded, otherwise the reason for the high latency or losses is something else:
a) The processor of the router is loaded
b) The quality of the transmission lines is
