            <title>[SERVER-3116] What is the default server connection pool size</title>
                <link>https://jira.mongodb.org/browse/SERVER-3116</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;We are running 1.6.3 server version with 1 master and 2 slaves.&lt;/p&gt;

&lt;p&gt;We&apos;ve 4 web servers using Java MongoDB driver 2.5.3. Each web server has 1 read connection pool of size 400 to all mongo servers&lt;br/&gt;
and 1 write connection pool of size 400 to master. &lt;/p&gt;

&lt;p&gt;We want to increase read connection pool size on the web server. However, we want to know what is the default connection&lt;br/&gt;
on sever. There is no information on the mongodb.org.&lt;/p&gt;
