So…?

I wrote the initial Get CPU Routine and got some feedback.? (See my prior writing for the link to that video).


Two of the suggestions were:?

A> Remove the SaveArea Logic from the routine because the SaveArea is not used which will improve the performance.?

B> David Staudacher wrote a version that used the Extract CPU Time instruction. ? Which the manual states is faster.?

I thought it would be interesting to see how much faster those routines were.?

Speed Testing 3 Get CPU Usage Routines

The video above, is using the Get CPU Usage routines to measure themselves.?


Also, I figured out why the original routine which was named CPUTIME would NOT work when invoked statically. (Hint: I got a suggestion on where to look).? I did the following video to explain what I did wrong:? Why Static Call to CPUTIME Got Invalid Results
