Did you try pinning the Ethernet IRQ to the last processor?

This usually make a large difference in Network latency

With your script the irq go to 2,3 core!
Code:
 26: 0 0 39646 4301 IR-PCI-MSI 1572864-edge enp3s0

I can't move IRQ on just core 3, it stays between 2 and 3.
I created 2 startup scripts that do nothing but move irq at startup to be sure I used smp_affinity_list + smp_affinity but nothing core 2 always has to do with IRQ 26! Does anyone know a way to move it? Change kernel version? Now I'm with 6.1. 0-33-rt-amd64 in theory with an upgrade I should have 6.1. 0-34-rt-amd64 but I don't think it solves the problem.

Is it working? I don't understand what cat /proc/interrupts does maybe there are old values ​​before the switch to core 3?

That looks like its working since you are only getting interrupts on CPU 3
(CPU 2 interrupt count  is not changing)
