            <title>[SERVER-12332] choose std::sort or stable_sort for external sort</title>
                <link>https://jira.mongodb.org/browse/SERVER-12332</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Should do some performance tests of index building.&lt;/p&gt;

&lt;p&gt;Or figure out conditions under each is better so we can select at runtime.&lt;/p&gt;

&lt;p&gt;vectors to test:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;numbers of indexes&lt;/li&gt;
	&lt;li&gt;size of keys&lt;/li&gt;
	&lt;li&gt;size of index&lt;/li&gt;
	&lt;li&gt;regular build&lt;/li&gt;
	&lt;li&gt;multiple build&lt;/li&gt;
	&lt;li&gt;compact&lt;/li&gt;
&lt;/ul&gt;
