i&#39;m trying tuning the FS to max performance on centos 5.5, and referred to <br><a href="http://wiki.freeswitch.org/wiki/Performance_testing_and_configurations#FreeSWITCH.27s_core.db_I.2FO_bottleneck">http://wiki.freeswitch.org/wiki/Performance_testing_and_configurations#FreeSWITCH.27s_core.db_I.2FO_bottleneck</a><br>
<br>#1,  i configure the DB of FS to ramdisk ,<br><br>when i run &quot;tmpfs /opt/freeswitch/db tmpfs defaults 0 0&quot;, it output: &quot;-bash: tmpfs: command not found&quot;<br><br>#2,  i run &quot;ethtool -g eth0&quot;, the output is below, what value i should config for RX and TX for max performance...<br>
Ring parameters for eth0:<br>Pre-set maximums:<br>RX:             4096<br>RX Mini:        0<br>RX Jumbo:       0<br>TX:             4096<br>Current hardware settings:<br>RX:             256<br>RX Mini:        0<br>RX Jumbo:       0<br>
