So, I disabled HyperThreading (== proprietary Intel #smt implementation) on my Dell Inspiron 5567 laptop. So, I'll be ready when I see about up(dat|grad)ing tomorrow (or this weekend).

Apparently, having it enabled doesn't actually help most workloads. Context matters, in other words. I notice no difference on my laptop here. It doesn't feel instantly slower than it was ( haha :D )
