                <link>https://jira.mongodb.org/browse/SERVER-82511</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://github.com/10gen/mongo/blob/af39933b7e530cf1e582093fa06197ec6dd7799a/src/mongo/db/storage/wiredtiger/wiredtiger_record_store.cpp#L2182&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/10gen/mongo/blob/af39933b7e530cf1e582093fa06197ec6dd7799a/src/mongo/db/storage/wiredtiger/wiredtiger_record_store.cpp#L2182&lt;/a&gt;&lt;/p&gt;

&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;

			&lt;/td&gt;
		&lt;/tr&gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;  &#160; metricsCollector.incrementOneCursorSeek(c-&amp;gt;uri); &lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;
&lt;p&gt;This line of code implicitly constructs a StringData from a const char*, which results in a call to strlen every time we seek on a record store cursor. While this is not an enormous cost, it has shown up in some profiles I&apos;ve taken.&lt;/p&gt;</description>
