            <title>[SERVER-60116] Fix Excessive Pointer Arithmetics in the Buffer Builder</title>
                <link>https://jira.mongodb.org/browse/SERVER-60116</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;There is some complexity with the pooled buffer alloc, since it does not provide a pointer eagerly. &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=redbeard0531&quot; class=&quot;user-hover&quot; rel=&quot;redbeard0531&quot;&gt;redbeard0531&lt;/a&gt; hacked it in &lt;a href=&quot;https://github.com/10gen/mongo/commit/fcc2834417a232b48dc31c719200d05093f18977&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this patch&lt;/a&gt; and saw a noticeable performance improvement by eagerly doing the pointer arithmetics. On this patch, &lt;tt&gt;grow()&lt;/tt&gt; was written to be especially friendly to how compilers like to generate code.&lt;/p&gt;
