Question: Is there any performance impact having TRACE Nodes in a message FLOW?

Answer: Yes. The physical I/O generated from a Trace Node is both serialized and unbuffered with a wait after each line.

Don't leave trace nodes in a flow after they are no longer needed.

Just a little correction: ${Root} is not a good choice (only in dev), but a simple tracing is tolerable, mostly in batch traffic.

But if you need a real performance impact: change trace level to debug
