I have a machine which has 32 processor but i am really not sure how many threads are running. It has hyperthreading enabled. Is there a way i can find that all 32 processors are being used and how many threads are there in my linux box. Its a 64 bit processor. I am having very high load average problem on this box and recently increased number of processor from 16 to 32. It's a web server and still same problem. Can someone please advice.
See man page for ps and top. Try
ps -eLf
ps -eLf | wc -l

Hyperthreading does not double your cores. Doubling your cores would double your cores.
I wrote a script about cpu and system info long before.maybe it can be help:b:
