+# Implementation of asynchronous preemption feature https://github.com/kubernetes/kubernetes/issues/126858 is supposed to increase the throughput of the measured pods as all heavy operations (apiserver communication) will be performed asynchronously, without blocking the scheduler loop.
 # How is it achieved:
 # 1. There are X initial nodes with 4 low priority pods each, consuming 3.6 CPU out of the total 4 available.
 # 2. High priority preemption which need to preempt 3 of 4 low priority pods to fit (require 3 CPU).
