Hi Dear Friend I used Simple queue For limit 2G BW on 1072 Router Cpu is High
Now suggest to me limt BW By quee tree ( mikroitk suggest used Queee Tree mark Packet )

Now do this

chain=prerouting action=mark-packet new-packet-mark=Nakhl-IN passthrough=yes dst-address-list=nakhl-IPS in-interface=Internet-INPUT-VLAN log=no log-prefix=""

And limit RX packet by

name="Nakhl-IN" parent=global packet-mark=Nakhl-IN limit-at=0 queue=default-small priority=8 max-limit=2000M burst-limit=0 burst-threshold=0 burst-time=0s bucket-size=0.1
This Configuration True ????

Hey

Do you have another system to test these changes?

In this particular case I would take that "advise" with a HUGE grain of salt, or better yet: just ignore it...

Simple queues are processed by multiple cpu cores, which spreads the load. Do you see that? Try monitoring with /tool profile
On the other hand for a queue tree, linked to a particular interface, only 1 cpu will be used. Given your bandwidth of 2gb, i'm pretty sure that a single cpu will NOT be able to process that queue fast enough. You'll introduce a bottleneck.

Verify these remarks in your situation, to be sure.

But high(er) load is the price to pay for queueing high bandwidth.
