[Freeswitch-users] Load test - performance not even matching Asterisk

[Jon Bruel]

I have made some load test, where an Asterisk server was controlled to
make a high number of calls to a FreeSWITCH, which was registered on
Asterisk. Each had its own server. The calls made to the FreeSWITCH were
answered and echoed. The CPU load on the FreeSWITCH server approached
100 % at around 100 calls. Similar test with an Asterisk server would
show 2-3 times less CPU load. Looping back to the Asterisk, thus
avoiding a possible CPU-loading application (echo), did not show a
significantly different result.

The test has been done on a CentOS 4 and a FC8 with similar result. 

Any hints about how to increase the capacity to the level of several
times the level of Asterisk - as reported by others? Are we possibly
dealing with some hardware issues related to the NIC and its drivers.
