So, is it necessary to enable hyperthreading in BIOS, or does Linux just ignore that setting and utilizes the CPU's full capabilities anyhow? Yes, enable it if you want to take advantage of it. However, of late there have been some interesting articles that suggest that turning hyperthreading *off* may be faster than having it on. Care to share?
I suspect you can use google just as easily as I. I'm sorry, I don't have the articles on hand or bookmarked or whatever - why bother when google is better?
