Hyperthreading on vs Off | Penetration Testing

Hi, i want to know if there is a significant performance improvement when hyperthreading is turned on (or with a cpu that supports hyperthreading) over no hyperthreading (for example: with a cpu that doesn't support hyperthreading) ?

I used Google, and i read that virtualisation softwares (like: vmware, virtualbpx....) (which is big part of penetration testing) benefit from hyperthreading while doing other tasks on the host machine. But if i setup the machines i will test on a seperate computer (for example: laptop) that does nothing else, will there be any other task connected to penetration testing/IT Security that benefits from hyperthreading (on the main computer) ?

Note: the answer will affect directly my cpu selection in my next build.

Thanks in advance.
