Intel Hyper Threading Performance With A Core i7 On Ubuntu 18.04 LTS

Following the news yesterday of OpenBSD disabling Intel Hyper Threading by default within its OS over security concerns and plans to disable Simultaneous Multi Threading for other processors/architectures too, here are some fresh Intel HT benchmarks albeit on Ubuntu Linux. The OpenBSD developer involved characterized HT/SMT as "doesn't necessarily have a positive effect on performance; it highly depends on the workload. In all likelihood it will actually slow down most workloads if you have a CPU with more than two cores." So here are some benchmarks using a current-generation Intel Core i7 8700K six-core processor with Hyper Threading.

Apple's Late-2016 MacBook Pro Is Still A Wreck With Linux

At the end of last year we had a brief encounter with the new at the time MacBook Pro with Touchbar to see how well it would run under Linux. It was a mess with SSD difficulties, non-working touchpad/keyboard, WiFi issues, and more. It's a bit better using the newly-released Ubuntu 17.10, but would still advise against Linux for the Apple MacBook Pro Late-2016 model / Mac-A5C67F76ED83108C / MacBookPro 13,3 model.
