Interesting that two cores is faster.

Why does Qubes Disable Hyperthreading?

Question from a non tech savvy person. SMT = Hyperthreading? So Qubes disables hyperthreading? Why does Qubes do this? This essentially means that for Qubes there are only so called 4 “logical cores” if you got one CPU with 4 cores though it supports Hyperthreading, which would ammount to 8 logical cores. Thanks for all the answers. I am very interested in not only using it but understanding it as well. If you also got any good reads (books, blogs, wikis etc) on Intel-CPU, Xen, Virtualisa…

That post also seem to suggest that more isn’t always better.
