Overview
...
The purpose of these tests is to compare results from two identical test runs on different environment. Find the reason of slownesses slowness if any will be there.
Summary
...
Bot Both system shows are stable work, under load and test passed without errors. Environments has have a different logic on in modules usage, so there is a difference in response times there.
GCP1 env. shows faster response time than BHS1, less than 10 milliseconds difference on 75 percentile and less than 50 milliseconds on 95 percentile.
It's not a big diference difference, however with such request per second rates it causes a visible difference in total count of calls.
