CHANGE: switch performance tests to DynamicMeasurementCount()

[stefanunity]

Description

Performance tests are usually using MeasurementCount(X) to run tests X times and then calculate the average. Using DynamicMeasurementCount() (see manual) it dynamically finds a suitable measurement count based on the margin of error of the samples. (Jira ISX-1496)

Testing status & QA

• CI green

• data getting submitted to observer

• tests remain on implicit [Version="1"] as recommended by @marek-u3d

• the overall runtime of the CI is a bit shorter since it needs less iterations on more stable platforms to finish the test

• it is more stable in quite a few tests

• it is as (un)stable in most tests

• it is a bit more unstable in a handful of tests

• some tests are faster

• a handful of tests are a little bit slower

Overall Product Risks

• low risk, we are going to minitor them for a while and adjust if needed

• Complexity: low

• Halo Effect: low

Thank you! Much better to have iteration count derived from observed statistical variance.
