Hi list I have a server with SMP and the CPUs support HyperThreading. I can start domU on cpu = 0, cpu = 1, cpu = 2 and cpu =3. I read that there's basic support for HyperThreading, what does this mean? And how is performance on 0,1,2 and 3 with HyperThreading compared to non-HyperThreading CPUs 0 and 1? Is 2 weaker than a non-HyperThreading 0? Would it better to disable HyperThreading with noht as boot option? -- Med venlig hilsen / Best regards Lars E. D.
