Subject [jira] [Commented] (HBASE-11585) PE: Allows warm-up
Date Fri, 25 Jul 2014 11:49:39 GMT

Nicolas Liochon commented on HBASE-11585:
-----------------------------------------

bq. shoudn't we update the start time or at least have another start time based on when the
warmup has completed?
In my tests, it was not an issue because not warming up impacts a lot the 99+ latency percentiles,
but the mean time (and as such the global time) it not really impacted.

> When we measure the latency, warm-up helps to get repeatable and useful measures.
