Turning FFDC off dropped OVWDB performance from 50% of a CPU to 15% - results
aren't "conclusive" but sure seems dramatic to me.

Jane,
this are two complete different things.
The Autotrace is more like a (source) code trace.
You (no, not you ;-) see what code has been executed during the snapshoot
... with FDDC before the core happens.
Similar to the dbxprof tool you might got from support in the past to look
whats going on if you have performance problems or have found a possible
loop.
The nettl subsystem only trace things what the developer though what is
worth to (in different classes, subsystems).
But I might be wrong and some other guys know it better.....
Kind regards

Many thanks, Oliver,
Does this mean that the nettl subsystem is now redundant? It still
seems to run as ever, although I almost never had cause to use it.
Cheers,
Jane
