In the attached screen shot a build which took ~23 mins can be seen. However the actual build steps in reality were fast. i.e. Less than 2 mins. Most the time was spend waiting to acquire a slave. It'd be great if Blue Ocean could show the length of time it took to acquire a slave. e.g. For the Code Signing - OSx step below it could have a Waiting on Slave step as the first part of the UI indicating it took 10 mins to acquire.
