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
