More updates into it, what it looks to me is like the switch is doing everything in software.

Latency is very high with a single port, and the more features I add the more cpu it takes.

If switch is behaving like this with no traffic I cannot put in into production. I am still hoping maybe for a quick setting that I am missing before RMA the switch.

More info below, and yes it's a Dell refurbished.

Hi, need to bump this up, I can still see this issue on some switches including the m8024-k ones.

Thank you Antonio
I can confirm the performance is not being affected so is just a cosmetic issue.
Not using ipv6 for MLD yet, disabled via sdm

Ok, MrRack. Glad to know this is not a real issue.

Thank you for your feedback.
