I don’t know if there’s a higher-level API, but the raw “PerfMon”  
counters are stored in the Registry and can be grabbed using a Registry  
reader.

See sys-proctable.

I think the gem is broken at the moment. If you have a problem, go to  
[http://www.rubyforge.org/projects/sysutils](http://www.rubyforge.org/projects/sysutils), download the sys-proctable  
zip file and install it manually.
