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.
