<p>What is the difference between using this</p>

<pre><code>[self performSelectorOnMainThread:@selector(doStuff:) 
                       withObject:myObject 
                    waitUntilDone:YES];
</code></pre>

<p>instead of simply</p>

<pre><code>[self doStuff:myObject];
</code></pre>

<p>in terms of CPU load? Or there are any other advantages?</p>

<p>thanks.</p>
