Thanks Mark for mentioning my presentation. It was actually the first one
in my "troubleshooting the most complex performance issues I've ever seen"
series and the slides are still available here:
https://www.slideshare.net/tanelp/tanel-poder-troubleshooting-complex-oracle-performance-issues-part-1
I think I have done 4 such presentations over time (most should be
available in Slideshare). Maybe it's time to re-deliver these online -
they're lots of fun! ;-)
Thanks,
Tanel Poder

Tanel wrote up a classic performance track down at Hotsos several years
ago where no waits were traceable to the Oracle engine and he had to get
all the way down to “find the file” in subroutines before the problem
became apparent.
