Hi All, I am curious that how is the credit scheduler compared to the linux default CPU scheduler ? They look quite similar. Do the problems in the credit scheduler also exist in Linux CPU scheduler?
What I understand is that, virtual machine monitors have a higher requirement in "fair sharing" than Linux. Therefore, we need credit-based scheduling which can possibly cause problems for latency sensitive workloads.
Thanks
