            <title>[SERVER-27171] Add operator&lt;&lt;(bool) to StringBuilderImpl</title>
                <link>https://jira.mongodb.org/browse/SERVER-27171</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Running the &quot;Queries.IntNonIdFindOne&quot; mongo-perf test while profiling mongod under VTune shows the StringBuilderImpl operator&amp;lt;&amp;lt;(int) as a significant hotspot. This stems from writing boolean values to StringBuilder in the read/update/delete path during query planning. As we don&apos;t implement a boolean stream handler, booleans are handled as type int, and are written inefficiently via snprintf. A boolean operator can be written that will perform the same action in a (much) more efficient manner.&lt;/p&gt;</description>
