The following output is quite common, for example in https://logs.opendaylight.org/releng/vex-yul-odl-jenkins-1/bgpcep-maven-verify-neon-mvn35-openjdk8/831/console-timestamp.log.gz :

Note that while the test ran for 42 seconds, an additional ~31 seconds is spent waiting for ... something ... to happen. The delay seems to fluctuate between 29-31 seconds, oftentimes it's not there at all.

This is extremely inefficient and hurts especially projects with a large number of features - as these delays pile up rather quickly.
