Assunto: [CentOS] Enable HT on CentOS 6.4 (Dell R720 64 Bit server)

I have HT Feature available on my Dell Server R720. Please help me
understand if HT is enabled on the server, will there be a
performance impact. What are the deciding factors to enable HT on the servers.

Hi,


    If you had HT enabled on the BIOS, the SO will "see" two times de cores
you had on that machine. The Linux kernel will use it, and possibly will give
some performance gain. But, for sure, you will need to try with your install
and application to guarantee that there is really some performance impact.


    Att.,


        Antonio.
