Добрый день!

Есть сервер HP 180 G6

 

Хочу сделать распределение нагрузки на ядра процессора

подскажите как правильно раскидать

 

сейчас вот такая картина

недогруженный CP4 CP6 CP7

 

в основном трафик идет eth5

cat /proc/interrupts

подскажите как правильно раскидать

прибить очереди к ядрам.

 

к слову, ядер-то у вас всего 4, и возможно отключение гипертрединга уменьшит нагрузку...

82576 должна создавать по идее по 8 очередей же ? А здесь же всего по 1 очереди от каждой с совмещёнными векторами.
