New Versions of my system monitoring applications are available from https://armclub.org.uk/free/

!APPstat	Monitors events and messages delivered to all running applications, displays call counts and time spent in applications to microsecond accuracy.
!SWIstat	Monitors SWI call activity on entire machine or selected tasks.
!SERVstat	Monitors Module Service call activity on entire machine or selected tasks.
!VECstat	Monitors calls to system vectors with reason code display, for the entire machine or selected tasks.
!CPUload	Improved CPU usage application, supports multiple windows and displays load of entire machine or selected tasks.

The main improvement of the stat apps is the use of the desktop font for the counter displays. Previously system font was used to minimise the performance overhead on ARM 2 machines, but modern machines are a bit quicker now. On my slowest machine (Iyonix) CPU usage increased from 0.7% to 1.3%.

The module used by !APPstat and !CPUload has incorporated a work around for ARMx6 machines which stopped sub centi-second timing working.
