How well do Linux and Windows handle variation in CPU core performance?

Question

These days CPUs can have multiple cores with different performance specs, some slower, some faster.Until now I&rsquo;ve just trusted that the OS Kernel knows best how to balance the load. But that was when all cores had the same performance.So I&rsquo;m wondering how well do Windows and Linux handle modern CPUs?What challenges are there to tasks scheduling on modern CPUs?

I forget what the situation with arm is.Intel had been very busy making a new cluster scheduler for heterogenous cpus. https://www.phoronix.com/news/Intel-Cluster-Sched-Hybrid-V2
