Re: st: 50% CPU Performance, Stata or Computer?

[Andrew Shephard <andrew_s@ifs.org.uk>]

I suspect it might be because you have a CPU which supports 
HyperThreading (HT). If this is the case then there is nothing to worry 
about. My understanding (correct me if I am wrong), is that HT 
essentially makes you computer think there are two CPUs (look in your 
System properties). If you are just seeing 50% usage then it just means 
that Stata does not support HT and so does not have any performance 
boost as a result of this.

If you disable HT (which you can typically do in the BIOS) then I would 
expect that CPU usage would shoot up to 100%. However, the actual 
performance which you get will be the same.
