R80.20 VSX Perfomance Optimization Questions - MultiQ, CoreXL

Jump to solution

Hello,

I have seen, that one of my cores is nearly always on 100% si. It's one of our 10GE interfaces that leads to our internet firewall.

So I tried optimization by using MultiQ and CoreXL Affinity.

Now I see still 100%si on one of the cores. Did I made something wrong or how would I get more cores for MultiQ?

Maybe somebody can give me a clue.

Thanks in advance,

 

Jan

 

 

Here is my configuration:

Checkpoint 23800 VSLS (at the moment all machines are running on one member)

VS5 is the bigest machine (10 COREXL) and VS4  (4 COREXL) is another machine. The other VSs are Virtual Switches. Some (2 or 3) of them will get unnecessary, but I didn't have enough time in the last maintenance window.
