<p>Hello,</p>
<p>Can you check with netstat the recv and send queues for the
sockets used in this communication? If the recv queu for receiving
up is big, then it cannot handle the traffic fast enough.</p>
<p>Cheers,<br>

</span>Do you mean that the objective rate at which the
client receives the<br>
messages decreases, or that a very large amount of them end
up buffered<br>
