Symmetric Multiprocessing Scheduler Improvement Forthcoming in Kernel 4.3

Thanks to Phoronix, here’s the Git entry.

This might actually substantially improve performance on KVM hosts with multicore guest domains, especially those with overcommitted processors.  Though I haven’t seen it specifically mentioned, theoretically, I’d imagine the dynamic symmetric multiprocessing workloads foisted upon those systems supporting multiple multicore guest domains to constitute the primary class of Linux kernel implementations likely to see benefits from this improvement.

So start thinking about ways you might be able to take some good performance benchmarks now, if you’re interested!  I’m very interested in seeing how this turns out.
