	After doing some more digging I have figured out what the issue is, am I right in assuming that you are running your code in Debug mode within VS?</p>
<p>
	This problem relates to a bug in one of the data structures used from a third party library that primarily manifests as slow performance under the debugger because of the use of a try catch pattern to detect a particular feature. See <a href="http://dotnetrdf.org/tracker/Issues/IssueDetail.aspx?id=317">CORE-317</a> and <a href="http://dotnetrdf.org/tracker/Issues/IssueDetail.aspx?id=292">CORE-292</a> if you are interested in more of the background to this.</p>
<p>
	The version of the library used in the latest trunk and which will be used for 1.0.0 has a fix which resolves this issue.</p>
<p>
	Here are the results of running your sample data under the debugger with different versions:</p>
<ul>
	<li>
		0.7.2 - 0.06s</li>
	<li>
		0.9.0 - 19.134s</li>
	<li>
		Trunk (1.0.0) - 0.09s</li>
</ul>
<p>
	However if you are running normally (i.e. not under the debugger) performance looks like the following:</p>
<ul>
	<li>
		0.7.2 - 0.06s</li>
	<li>
		0.9.0 - 0.9s</li>
	<li>
		Trunk (1.0.0) - 0.07s</li>
</ul>
<p>
	So this issue is resolved in the latest code and will be fixed in 1.0.0 plus it only applies when running under the debugger, I will mark this issue as Fixed for 1.0.0</p></td>
