  40. 40. BHL Technical Update BHL Load Testing Report  In 2017, at peak load one PageView occurred every 1.5 seconds.  Search PageViews made up 13.5% of all PageViews.  Assuming 13.5% of the peak PageViews were searches, the peak search load was one PageView every 10.7 seconds… about 6 searches per minute.

  42. 42. BHL Technical Update BHL Load Final Results • Despite the Max Observed Load of 8.22 for the 4-User test, the sustained load was closer to 5.0 for that test. Rarely did the load pass above 7.0. • The 5-User test had a sustained load of 6.0, and it was not unusual for the load to be at or above 7.0. • No 6-User test was performed, one can extrapolate that that is the level at which the recommended persistent load of 7.0 would be reached. This represents a level of search activity that significantly exceeds what BHL has historically seen, the ElasticSearch installation should handle the expected load.
