            <title>[JAVA-2143] Optimize ASCII BSON CStrings</title>
                <link>https://jira.mongodb.org/browse/JAVA-2143</link>
                <project id="10006" key="JAVA">Java Driver</project>
                    <description>&lt;p&gt;The 2.x driver has an optimized code path for decoding BSON CStrings that have been determined to be ASCII.  This was never ported to the 3.x driver, and the lack of it causes a measurable regression in performance.  We should consider porting it the 3.x driver.&lt;/p&gt;</description>
