----------------------------------------
Summary: Logging level DEBUG should be less verbose: "Fire Loop"
& "State was" should be trace
Key: DROOLS-1264
URL: https://issues.jboss.org/browse/DROOLS-1264
Project: Drools
Issue Type: Bug
Components: core engine
Affects Versions: 6.4.0.Final, 6.5.0.CR1, 7.0.0.Beta1
Reporter: Lukáš Petrovický
Assignee: Mario Fusco
Priority: Critical
In the latest 6.4 product patches, I am seeing customers that are up to *10 times slower*
due to drools in their optaplanner cases. It turns out that they have no logging
configuration and many systems - such as WildFly use DEBUG logging by default (often to a
file so no one notices it).
Meanwhile the log fills up with this:

but without the optaplanner TRACE lines (they are just here to show that drools debug is 7
times as verbose as optaplanner trace here).
Solution proposal A): remove the line "Fire Loop" and put "State was"
on trace logging.
Solution proposal B): collapse the 5 lines "Fire Loop" into "5 fire
loops" and put "State was" on trace logging.
Solution proposal C): put the line "Fire Loop" and "State was" on
trace logging.
I personally dislike this one - even trace logging should still be useful and not more
verbose that it needs to be (although it should log in high detail).
This should be fixed for 7.0, 6.5.x and I 'll ask QA to consider adding it for 6.4.x.
