I'd like to confirm that irq overlapping might be the issue, at
least it was a case for FreeBSD kernel.
We had a bad performance once on a freebsd based firewall. And it
turned out that embedded broadcom NICs and NICs on PCI shared the
same irq.
After reassigning them, processor load decreased almost 2 times with
much better throughput.
I've seen that too, but usually with USB.
The OP's interrupts looked well balanced though.
