Did you know you can display the amount of time a component takes to run?
Component profiling will let you display this time either as a percentage of total running time or in seconds.
Press Ctrl+T or Right-Click in the canvas and select Show Process Times to find bottlenecks, to find potential areas for improvement in your protocol, and to improve your protocol's performances !
Subprotocols will show the sum of time taken by internal components (open the subprotocol to see internal components run time) and overhead (if any).
