You will more than likely need to enable the features in the Bios of your server.

will enable hyperthreading significantly improve performance or there is some drawback?

[AndreTheGiant · Accepted solution]

It depends by the processor type.

On latest CPU there is no drawback and a little performance improvement.

Note that HT does not dupe the number or cores, but increse the number of logical cores...
