Nathan Roberts commented on YARN-6768:
--------------------------------------
Thanks Jon! As a datapoint, I have a testcase that measures how quickly we can
handle NodeUpdateSchedulerEvents when a user is at their user limit. This path
causes the ActivitiesLogger to be invoked at a very high rate. The most
expensive operation within the ActivitiesLogger is
application.getApplicationId().toString(). When I apply the patch on this jira,
the throughput improves from 22K/sec to 32K/sec.
