High System Interrupt CPU Utilization


neal9697

Recommended Posts

I'm new to torrents and I've been using uTorrent 3.2, as recommended by the primary tracking site that I download from (video files mostly). I've noticed that whenever I'm downloading that the Win8 Task Manager show a high percentage of CPU utilization (20-25%) attributed to System Interrupts. The amount of System Interrupts is proportional to the amount of Network Utilization.

It doesn't seem to be strickly attributable to uTorrent, as whenever there is a large amount of Network utilization (Windows Update download, etc.), the same thing occurs. So I tried a few other solutions that I found online first (i.e., uninstall/reinstall WLAN device drivers, etc.). I've tried using MS Windows Performance Toolkit to identify the culprit, but I'm a novice at this type of thing.

Based on a few other threads here, I took a HijackThis log (see below) hoping that you can provide me some advice. I'd really appreciate it.
