Hi,
we are currently using the tool “spin” (version 1.10) with QNX 6.2.1
on an x86 machine for a performance analysis. Unfortunately we get some unplausible results.
E.g. we get a CPU load of about 19000% when starting spin -c.
That seems to be a little bit too much, even though we know, that
our application can easily provoke a load of 100%. Is there a reason for
that enormous number. And possibly a way to reinterpret this result.
I made some adaptions to the 1.10 version of ‘spin’, so that ist also runs under QNX6.3
(specially memory and NIC statistics), if someone’s interested.
(Though: I didn’t manage to contact Igor yet, to post the changes to him, but hopefully this will happen within the next few days).
All my changes are for Neutrino V6.3.0 and later only, so that this version should still run under QNX 6.2.
From the change note in spin.c:
Change log:
1.11 - Adaption to QNX6.3.0, June 8, 2005, by Karsten Hoffmann (kphoffmann@ish.de),
- New interface for NIC statistics again
- Memory statistics interface changed as well.
- Date format changed to ISO-type
P.S.: Does anybody know, why this BBS complains about .tgz’ attachments, but it allows '.tar.gz’ files?! Wierd …
