process interrupts by multiply CPUs

[Коньков Евгений]

Hi

Can I allow to process interrupts from re0 by multiples CPUs

I get one CPU overload while other idle

last pid: 14902;  load averages:  1.92,  2.12,  1.96    up 0+17:47:31  19:59:04
226 processes: 12 running, 197 sleeping, 17 waiting
CPU 0:  0.6% user,  0.0% nice,  1.2% system, 88.3% interrupt,  9.8% idle
CPU 1:  1.8% user,  0.0% nice, 29.4% system,  0.0% interrupt, 68.7% idle
CPU 2:  3.7% user,  0.0% nice, 30.7% system,  0.0% interrupt, 65.6% idle
CPU 3:  3.1% user,  0.0% nice, 25.8% system,  0.0% interrupt, 71.2% idle
Mem: 264M Active, 1641M Inact, 272M Wired, 832K Cache, 112M Buf, 1721M Free

14867 root        46    0  9728K  1956K select  3   0:00  1.12% sudo

I have try to tune system how described on this:
https://calomel.org/network_performance.html
but that did not help.

Can you advice me something, to allow process interrupts by all CPUs?
