Just installed Proxmox on a new server with a Intel L3650 CPU. Proxmox is showing 8 CPUS when I believe I should see 4.
Code:
CPU(s)8 x Intel(R) Xeon(R) CPU           L5630  @ 2.13GHz

Anyone have any insight on this? Does this indicate a problem I need to fix? As always thanks for reading.
 
this cpu has 4 cores with HT (hypherthreading). if you do not want HT, disable it in the mainboard bios.

I thought that might be the reason, but I didn't see that in the CPU specs. Nice... 4 bonus cpus!
 
Well, a cake does not really get bigger if split into more pieces ;-)

Maybe it does. This ancient (2003) IBM developerworks benchmark shows a 30% performance boost in some multithreaded applications. So it may be good to leave it on. Still multiple cores + hyperthreading seems like redundant features to me, I guess that's why I didn't think hyperthreading would be a feature of that CPU. =)
