Interrupts Time

Exists in Windows NT/2000/XP only. It is a placeholder for hardware interrupts statistics. It also has pseudo threads for each CPU in system. You can see how much time CPUs "live" in interrupts in "CPU" and "CPU %" columns and how many interrupts per second are processed by each CPU in "Sw/s" field (see also description of process pane). You may be surprised how much time your system spends for processing hardware interrupts during active work with IDE disk in non UDMA mode! Note that executing of threads is blocked during processing of interrupts.
