0 on Windows and SunOS.
- **syscal**: number of system calls per second. Do not displayed on
Linux (always 0).
- **dpc**: *(Windows)*: time spent servicing deferred procedure calls.
To switch to per-CPU stats, just hit the ``1`` key:

# - irq (Linux, BSD): time spent for servicing hardware interrupts
# - softirq (Linux): time spent for servicing software interrupts
# - steal (Linux 2.6.11+): time spent by other operating systems running in a virtualized environment
# - guest (Linux 2.6.24+): time spent running a virtual CPU for guest operating systems under
