Is there a way to tell how accurate the timing is on a box before running FreeSWITCH on it? From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Anthony Minessale Sent: Wednesday, March 10, 2010 10:26 AM To: freeswitch-users@lists.freeswitch.org Subject: Re: [Freeswitch-users] Kernel timer warning with CentOS 5.4 FS now tries to determine how accurate the timing is by doing some tests with 1ms sleeps. Most 64 bit CentOS box I have seen can easily calibrate. If you are having that error alot but the calls still sound ok, it's safe to ignore it. you can also start FS with -nocal to skip this test. Also make sure you do not have any other cpu-intensive application on your box possibly competing for resources.

It seems to be variable. Most times (on CentOS 5.3) when I start FS it tells me it is around 1995ms. Occasionally it is lower (sub 1000ms) and then does not give a warning.

What number does it say it detected for the gap?

You may experience audio problems". I get no such warning if I build on CentOS 5.3, and the test timings it measures on starting FreeSWITCH do look lower. All I was doing to upgrade to Centos5.4 was a yum update on the 5.3 build. I guess the warning comes from here: http://fisheye.freeswitch.org/browse/~raw,r=16409/FreeSWITCH/src/switch_time .c <http://fisheye.freeswitch.org/browse/%7Eraw,r=16409/FreeSWITCH/src/switch_t ime.c> This is all on pretty low spec hardware - a couple of different Dell optiplex p4's I use for testing. Does anyone happen to know if I should just stick to Cent)S 5.3, or use 5.4 and not worry about the warnings, or if there is something I can do to fix the problem it is warning about. Perhaps it is just that I shouldn't use such crummy hardware?!
