When reading about performance testing, I came across the term "Coordinated Omission". I read several references [1], [2] to get an idea about "Coordinated Omission", but non of them provide the exact meaning of the term. Can someone give a simple explanation on what this means? Also does Coordinated Omission occur in JMETER tool?

The problem is that the benchmark omitting the waiting time of the threads executing the tests while calculating latency:

Record the latency of response time - request time

JMeter is also record similar the duration, but you can set ramp up period of thread group to 0 to reduce the actual waiting time and thus the "Coordinated Omission" Also follow JMeter's best practices, specifically reduce resources tips (as run in non GUI mode)
