Hello Denys, I've installed sysstat (good tools!) and the result is very similar to the one which appears at top, take a look: 13:34:23 CPU %user %nice %sys %iowait %irq %soft %steal %idle intr/s 13:34:24 all 0.00 0.00 2.72 0.00 0.25 12.13 0.99 83.91 16267.33 13:34:24 0 0.00 0.00 21.78 0.00 0.00 0.00 7.92 70.30 40.59 13:34:24 1 0.00 0.00 0.00 0.00 0.99 24.75 0.00 74.26 4025.74 13:34:24 2 0.00 0.00 0.00 0.00 0.99 24.75 0.00 74.26 4036.63 13:34:24 3 0.00 0.00 0.00 0.00 0.99 21.78 0.00 77.23 4032.67 13:34:24 4 0.00 0.00 0.00 0.00 0.98 24.51 0.00 74.51 4034.65 13:34:24 5 0.00 0.00 0.00 0.00 0.00 0.00 0.00 100.00 30.69 13:34:24 6 0.00 0.00 0.00 0.00 0.00 0.00 0.00 100.00 33.66 13:34:24 7 0.00 0.00 0.00 0.00 0.00 0.00 0.00 100.00 32.67 So, we can assure that the IRQs are not being balanced, and that there isn't any processor overload.
