1.3 RC1 Performance regression, high CPU usage

@Dmitry thanks! Please see screenshot of perf top. Bandwidth did drop a bit while running perf top.

Hm. @erfus how I can reproduce this locally? Could you describe?

@Dmitry vyos is running on a KVM VM on a very low power board. (pcengines APU4). WAN PPPoE, NAT inside private subnet, a few basic firewall rules, nothing special.

Do you want me to try it bare metal on this board?
