Hiya,
I am wondering if there will be any performance overhead of including an inactive trace node in the main path(not error/catch path).
Basically, we will keep the tracing turned off all the time. But if there is any issue or requirement we will just turn trace on and capture the messages for troubleshooting etc.
Any suggestions? sorry i couldnot find any documentation on how '-n off' behaves, whether the node routine is still stacked except nothing being written(in which case i would presume a slight performance overhead) or it is the node completely ignored?
Thanks,

The performance overhead has been measured pretty consistently at three percent for inactive trace nodes.
This means if your Broker-latency is measured at 100 ms for a flow sprinkled with no trace nodes in the flow, the same flow will have a latency of 103 ms for inactive trace nodes that have been disabled.
This also means that if your flow in your DataFlowEngine process uses around twenty percent CPU, it would use twenty point seven percent CPU with inactive disabled trace nodes.
This being the case, the performance impact is negligible.
