Performance tests
We currently have very little measurement on how the Descheduler performs at scale. Issues like https://github.com/kubernetes-sigs/descheduler/issues/774 highlight this lack of information.
It would be good to provide benchmarks and identify changes/new strategies in particular that cause memory or performance degradation with a set of perf-scale tests similar to what the scheduler offers. To start these could measure descheduling throughput and memory consumption end-to-end as well as for individual strategies
@damemi, I'm thinking if this could be broken into parts with tests either based on strategies or different criteria like types of cluster( KIND or managed K8s cluster by any cloud provider).
Can these be used as a starting reference: https://github.com/kubernetes/perf-tests ?

@pravarag yeah, I think ideally this would be at least broken into tests for individual strategies (so we can identify which strategies suffer the most)
