> Tomorrow we'll rearrange everything and redo all the testing. One more item: when running the test with 20 x 2-vCPU VMs, make sure that the "-P" option is being used. This forces bhyve to do a vmexit when a PAUSE instruction is hit e.g. when the locking code starts spinning. This gives the scheduler more opportunity to run something else rather than letting the VM go until it's quantum expires. later, Peter.
