Looking at a recent flamegraph of the jobqueue, it seems 23% of the wall time in the jobrunners is just being spent on queuing CirrusSearch jobs. @dcausse looked at these jobs and they don't contain anything large. In fact, the time it takes to write the actual content to Elastic is around 3% while pushing the jobs that contain only metadata is taking 23%.
An edit in wikidata is also similar. XHGui says 2 seconds (out of 3.3 seconds) has been spent on queuing 10 jobs.
