Nextcloud system repport - core(threads)repport

Hi. I dont know if there are problem about… but i just have to get it out there. I was reacting about how "System - Administrations " see cores on the CPU, in my case the system says that i have 8 cores when i am siting on a Xenon E5620 that has 4 cores and 8 threads. so if you see what i see so?! hope this thread had meaning.
