Philip Harvey reassigned QPID-4517:
-----------------------------------
Assignee: Robbie Gemmell (was: Philip Harvey)
Robbie - what do you think about this change?
Informal testing showed a x2 throughput improvement when using transient
messages and with DEBUG logging enabled.
Obviously in most production deployments the speed-up will be much smaller.
> Java Broker: default log4j configuration outputs line numbers, which is a
> performance drag
