Hi,
I've been studying the question for years, without succeeding to make my mind about it.
So far, I only took servers with 4 "real" cores , and no HT . In a near future, I'll change one of my server, and take a 4 cores 8 threads CPU (I made my choice based on the offer, not the CPU model).
I often read that HT only profits to very specific applications, which are multi threaded , and which are using Intel's special set instructions.
So for a server using common applications linux / apache / nginx / php / mysql / mariadb, is it better to disable the HT ?
Regards,
