In 4.x, it was a 'shut it off' sort of deal .. my new amd64 don't

Is it still something that I should disable, and, if so, how in 6.x?
You should test it for the workloads you have, but most of the time, HT
isn't especially helpful. AMD64 CPUs come in dual-core format rather
than HT-enabled. If you've seen "HT" or "HTT" applied to an AMD system,
it's likely an abbreviation for "HyperTransport" or "HyperTransport
Technology".
