CPU load v6 much higher than v5 same router same traffic

RouterOS General
1

I will try to keep a long story short. It all started with the following patron with routeros v6.7

In Green the uptime and the other colors are the load of each core.
(notice at first I only monitored the first core. I add mid-march the other cores after investigation)

Conclusion, the system gets busier when the uptimes gets higher.


Let’s look at the traffic patrons during that period.

Not the same patron, doesn’t grow and goes low again like the cpu load.

If I magnify the memory use vs uptime during the same period I get this

Same like cpu load. I know it’s not a lot of memory difference, but same patron.


To solve the issue I tried some more v6 version:

Strange things, I want to understand why the cpu load rises and the traffic doesn’t. Downgrade to v5.26 show the old trends I always say.


Long term trend view… (please ignore the DDOS period)


The router is running about 8 bgp peers, 2 ospf peers, 300k bgp routes, 50 ospf routes, no conntrack, x86, 20 forward firewall rules.
I can’t help that I think something is going wrong. I understand that v5 and v6 report a different value for the same traffic but it should be linked to the load / use and should not build up when the uptime becomes more. The problem is not really an issue since the router can handle the load. When v6.13 is available i will test it again, for now i will keep running v5.26.

I will keep you all informed. Tip / suggestions are welcome about this problem.

Hello,


I will try to keep a long story short.

And here is the short answer, MikroTik adds to RouterOS continuously
new functions, options and/or features mostly based on the willing of
their clients and customers and so the entire system will be growing up
more and more and is also using mostly more cpu and ram resources.
That is it easy and short.

Think on a former server from the year 2008 and now you want to install
MS Server 2012, not related to the drivers and hardware support but more
on the entire remaining system.

And one question by me if you are willing to answer, what was standing in front of the
CPU uptime? What kind of cpu you where using, would you please so friendly and tell me this?

Hi Kreacher,

Thanks for your responds. Seems that I posted my story twice.
Sorry about that. My first post on this forum whent wrong due to the very long human verification time.

Please check the other tread it contains more information. I will add the cpu specs shortly.
