Does SMT still make sense?

Whatever machine you’re reading this on, it’s highly likely that not all of the CPUs shown by the OS are actually physical processors. That’s because most modern processors use simultaneous multithreading (SMT) to improve performance by executing tasks in parallel. Intel’s implementation of SMT is known as hyperthreading, and it was originally introduced in 2002 as a way to improve the performance

最近のCPUはコア数が多いので、SMT(マルチスレッド)機能は不要なのではないか？セキュリティ的にもSMTはオフにしたほうが安全。
