Dieter - I don't believe I compared performance between the 2 options -
I said that journaling performance is no longer the problem it used to
be 25 years ago, when many people rejected journaling for that reason.
As to triggers, there is a potential for a performance problem, due to
the synchronous nature of calling triggers.
NOTE - these are mutually exclusive - they have nothing to do with one
another.
So there was nothing where I replicated myths. Done! and Done!

Comparing journaling with a trigger, writing a record (something like ashortened trigger image):
- read operations: no diffrence to the same operation with none of thesea low level operation
- insert operations: journal will outperform the trigger by far!!! it's
- update/delete operations: the trigger might be better (has to beevaluated), if it is not fired for this operation. If you would need
triggers for this too: journal will outperform triggers by far!!!
