<div class="moz-cite-prefix">You shouldn't feel any performance
issues after increasing tcp_max_conn to 4096. Connections hash
table size is pretty high (1024) so it's not a problem at all. Of
course if you want to handle twice bigger number of simultaneous
clients you need to check if you current hardware can handle it
(RAM, CPU).<br>

Is there any performance issue if we double the
tcp_max_connections ?. <br>
<br>
<br>
</div>
<div>Currently we are setting these parameters for TCP. <br>
<br>
tcp_connection_lifetime=3605<br>
tcp_accept_no_cl=yes<br>
tcp_rd_buf_size=16384<br>
<br>
</div>
<div>Do we need to tune any other variable if we are setting max
tcp connections to 4096 for better performance ?<br>
<br>
</div>
<div>Thanks for looking into this. <br>
<br>
Regards<br>
