high load CPU for a CHR working QT

Tue Dec 15, 2020 12:27 pm

Hello,

I install a CHR v6.47.8 in ESXi 6.7U3 host on an HP DL380 Gen10 with XEON-S 4208 processor, with Intel 10G NIC.
I allocated 32 cores for the CHR with 32G RAM and 16G HDD.
On CHR, I create a queue tree for a total bandwidth of 650 Mbps
When the Queue Tree (PCQ) is working, the CPU becomes unstable, sometimes the CPU works 15% and others reach 100%
when the queue tree is disabled, the processor works normal 12% and becomes stable.
Any idea for this issue please ?

Thanks

Queue Tree works on one CPU. If there's heavy traffic, this CPU get 100%. It's better to find a way using Simple Queues, so the workload is balanced over different CPUs.
Please, post your config and what do you want to achieve, maybe someone here can optimize it.

A simple configuration which was made in the CHR, we put it to manage the bandwidth.
CHR connected to a group of NASs (all are Mikrotik), they acts as a pppoe server on our network, 2000 active subscribers.
Queue Tree (PCQ) configured as the image 1 :

There are various configuration items that can be optimized to improve performance on your CHR at the moment.

There are multiple posts here as well as Wiki articles, alternatively contact a certified consultant closest to you https://mikrotik.com/consultants
