[Freeswitch-users] Timing issues in AWS?

Thu Nov 17 16:03:22 MSK 2011

Not having anywhere near the same trouble in a Xen Server in my lab...

Although test_time is skewed 180 degrees from what it was in AWS....

freeswitch at internal> timer_test 120 10

Thoughts as to why AWS results are so different from XenServer?  Other than
not knowing who else is on the AWS box?

Thanks,
