Can someone do the experiment to determine if disabling hyperthreading has the same effect on latency as isolcpu'sing all the vcpus that share the L2 of the last vcpu? I bet it does, and it'd have the nice benefit of not turning off half the non-realtime vcpus. -- Sebastian Kuzminsky ------------------------------------------------------------------------------ Dive into the World of Parallel Programming!
