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.
