            <title>[JAVA-4629] Lock free server session pool</title>
                <link>https://jira.mongodb.org/browse/JAVA-4629</link>
                <project id="10006" key="JAVA">Java Driver</project>
                    <description>&lt;p&gt;&lt;tt&gt;com.mongodb.internal.session.ServerSessionPool&lt;/tt&gt;&#160;currently users&#160;&lt;tt&gt;com.mongodb.internal.connection.ConcurrentPool&lt;/tt&gt;&#160;to implement its pooling behavior.&#160; ConcurrentPool has synchronization overhead that is unnecessary based on ServerSessionPool usage of it.&#160; We can improve the efficiency of ServerSessionPool by replacing its use of ConcurrentPool with direct usage of ConcurrentLinkedDeque.&lt;/p&gt;</description>
