Atomic variables on gcc 4.4.6 are extremely slow
<p>i am using gcc 4.4.6 and atomics can be accessed by <code>#include &lt;cstdatomic&gt;</code> . After using them, i realized they are very very slow. Finally i came across a post on stackoverflow, which describes it here <a href="http://stackoverflow.com/questions/13135834/stdatomicbool-is-very-slow">std::atomic&lt;bool&gt; is VERY slow</a></p>

<p>But i am not able to follow it. Can someone please help me understand that post or explain why atomics in gcc4.4.6 are so slow?</p>
