Hi, I'm curious how you got no hyper threading on your system. Do you disable it in some BIOS settings, or you have a really old processor?

It’s not a particularly old processor (it’s an i7 CoffeeLake arch, which I believe is from 2018/19). I believe intel did not include SMT in that arch. SMT is often looked down upon from a performance standpoint. While the idea sounds good (filling a pipeline with instructions from multiple threads), the fact is that memory is much more important, and the cost of two threads competing for the same limited cache space can be really bad for performance. There’s also been a number of security concerns related to SMT over the past few years that have caused some concern.
