Re: [Iometer-devel] Processor speed reported over 4294 MHz gives (very) wrong results

[Vedran D. <ve...@ya...>]

Hi Wayne,
 
You should try downloading a later package from here http://sourceforge.net/projects/iometer/files/iometer-devel/1.1.0-rc1/ or snapshot the latest SVN sources for even newer changes. There've been some improvements since then.
 
Regards,
Ved
