Yes Doug, that QB5SERVER is the debug server that is tracking every line
executed. We did invest some time speeding this up as much as we could,
but there is a performance penalty to pay for all of the debugger overhead
that basically has a breakpoint on every executable line of the programs
you are analyzing.

Hi Doug, IIRC I think you will find that the code coverage is basically
stepping through the program with the debugger so the performance will
not
be as fast as normal runs. The coverage data gets written to a file so
I
guess you could write a tool to read the incomplete file and display it
somehow though locking on the IBM i may prevent that.
All th ebest, Mike

Sent by: "WDSCI-L" <wdsci-l-bounces@xxxxxxxxxxxxxxxxxx>
I am testing a program I have written using Code Coverage. The results
it
gives are very good in terms of feedback of what I have tested and the
percentage of each subprocedure tested, etc. However, I notice that when
I
test using Code Coverage, the testing session is SLOW. I am testing a
green screen application, and the response time is very long. I checked
WRKACTJOB, and see that there is one QB5SERVER job that is racking up
CPU
with my userid assigned to it.
Does anyone else experience this? Is there a setting somewhere that
needs
to be changed to speed up the session? This is running on a DEV box with
a
very small workload.
Also, does anyone know if there is a way to have the Code Coverage
results
be displayed dynamically so I can get as high a "Covered Code" as
possible
in one session? Just curious.
I am running version Version: 9.6.0.9 20201112_1147
