For example, from the shell, time your script using "time <script.sh>". You will probably get a time around 10ms. This should not be a concern, and would be difficult to improve.</div>

You can perform a few quick tests to see where your issue lies: Use the freeswitch logs to see what the total time of the system call is, and then use the "time <script.sh>" to see what the time is from the shell. I think you will find that the issue is "system" and not the script itself.</div>
