Many CDNjs vs one minified local js : 

<pre><code>&lt;script src="//cdnjs.cloudflare.com/ajax/libs/jquery.inputmask/3.3.1/jquery.inputmask.bundle.min.js"&gt;&lt;/script&gt;
&lt;script src="//cdnjs.cloudflare.com/ajax/libs/numeral.js/1.5.3/numeral.min.js"&gt;&lt;/script&gt;
&lt;script src="//cdnjs.cloudflare.com/ajax/libs/Ladda/1.0.0/spin.min.js"&gt;&lt;/script&gt;
&lt;script src="//cdnjs.cloudflare.com/ajax/libs/Ladda/1.0.0/ladda.min.js"&gt;&lt;/script&gt;
&lt;script src="//cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js"&gt;&lt;/script&gt;
&lt;script src="//cdnjs.cloudflare.com/ajax/libs/bootstrap-modal/2.2.6/js/bootstrap-modalmanager.min.js"&gt;&lt;/script&gt;
&lt;script src="//cdnjs.cloudflare.com/ajax/libs/bootstrap-modal/2.2.6/js/bootstrap-modal.min.js"&gt;&lt;/script&gt;
</code></pre>

<p>vs</p>

<pre><code>&lt;script src="/myMin.js"&gt;
</code></pre>

<p>(myMin.js will contain all js file concatenated together and minified)
What is the best for performance? I am using cdnjs because it solves the problem of people in other region downloading the js file directly from my server. For example, people in Asia don't have to download my js file from USA server, which is a huge performance issue. <code>cdnjs</code> helps me with scattering js file all over the globe.  Since cdnjs is downloaded asynchronously so when will <code>myMin.js</code> be preferred?</p>
