В DispatchMon без галочки в CPU to monitor: CPU 0 нет ничего, а с ней наблюдается огромное количество ISR и DPC, идущие друг за другом, с драйвером ndis.sys во время просмотра видео на Youtube и торможения компьютера. При подключении к интернету через ADSL и отсутствии торможения такого количества ISR и DPC c ndis.sys нет.
В утилите kernrate Interrupts rate во время торможения 46871/sec (компьютер тормозил периодически), но NDIS составляет всего 1%.
Лог kernrate при подключении к Интернет через Билайн, просмотре видео на Youtube и торможении, Interrupts rate = 46871/sec:
