Hi,<div><br></div><div>In a previous email i was working on a benchmark, for examining performance changes between ITK3 and 4. I thought it would be handy to print the system info in the benchmark result, to keep track. So, i used itksys::SystemInformation. However, the results seem... questionable. its worth noting they seem the same between ITK 3 and 4.</div>
<div><br></div><div>The code that generated this is here <a href="https://github.com/rupertbrooks/itkbench">https://github.com/rupertbrooks/itkbench</a></div><div><br></div><div>Its worth noting that itksys::SystemInformation doesnt seem to be documented, so perhaps im just breaking all the rules here. Should i JIRA this?</div>

<div>My employer is not so cheap that we are still using P3s :-) CPUID reports it as a Intel Xeon W3530 Bloomfield. Core i7 would be a fine identification as well. Also, theres not 4 chips with 1 core each, but 1 chip, with 4 cores. This might be me misinterpreting the meaning of physical vs logical, but see below.</div>

Theres one physical chip, with 4 Core2 architecture cores on it. So strictly speaking, its a Core2 Quad. /proc/cpuinfo gets it as model name : Intel(R) Core(TM)2 Quad CPU Q8200 @ 2.33GHz</div>
