Hi Tim,
We are in the process of retesting everything with the following branch: https://github.com/digitalocean/linux-coresched/tree/coresched/v4-v5.5.y
The CPU-intensive case that becomes overcommitted when we disable SMT behaves the same as before (core scheduling is a clear win there). So we are now digging a bit more in our mixed tests with CPU and IO (MySQL benchmark running in parallel with low-activity VMs). The tests are still running, but I expect to be able to present some numbers tomorrow.
We will keep the list informed.
Julien
