Currently, we have a very crude logic for computing scheduling-throughput. We list all pods every 5s and see how many new pod very scheduled in that time. It doesn't work well in small tests where number of pods is low as we only get 1-2 representative 5s windows.

We should rewrite it to make it more reliable and accurate, e.g. use prometheus query to monitor rate of pod bindings

Currently, new prometheus metric is already implemented and data is collected for all tests in master branch.
It's worth to mention that previous SchedulingThroughput allowed us to gather metric with interval 1s, based on Prometheus we are only able to gather with interval 5s.
The only thing remaining is turning on alerting for specific tests and removing old SchedulingThroughput. I've postponed this step, because it might have been conflicting with merging density with load test.

only able to gather with interval 5s.

Unless we start scraping metrics more/less often. We may consider scraping more often potentially too.

I've postponed this step, because it might have been conflicting with merging density with load test.

Which is the right decision :)
Though we're almost done with this merging, so we will be able to get back to it.
