4 <title>Inaccurate Windows CPU Usage Reporting</title>

7 <p>
8 CPU usage reporting tools which come with Windows, such as Task
9 Manager or Resource Monitor, do not take the time spent
10 processing hardware interrupts into account. If the interrupt
11 load is heavy, with thousands of interrupts per second, CPU
12 usage may be significantly underreported.

14 <p>
15 This problem affects Windows as both host and guest OS.
16 Sysinternals tools, such as Process Explorer, do not suffer from
17 this problem.
