More tests around latency metrics

⏳ More ways to test latency

We’ve added more ways to test latency. Beyond just mean, max, and total, you can now make test latency with minimum, median, 90th percentile, and 99th percentile metrics. Just head over to the Performance page and the new test types are there.

You can also create more granular data tests by applying subpopulation filters to run the tests on specific clusters of your data. Just add filters in the Data Integrity or Data Consistency pages, and the subpopulation will be applied.
