Hello,
Several people asked to get a hold of the stats I used to determine that the
Sangoma T1/E1 boards performed better in our real-world tests than the
Digium boards. We've decided to post our results after confirming them over
the past month of operations.
Here is a link to the last two reviews I wrote about Sangoma with Asterisk:
http://astguiclient.sourceforge.net/Sangoma_experience.txt
Here is a summary of the production environment that these servers were
evaluated in and the hardware used.
HARDWARE:
Each server was constructed in house with the following components:
- 4U rackmount server chassis
- Asus P5AD2 motherboard
- Intel P4 3.2GHz Prescott processor socket 775 with 1 MB L2 cache
- 2GB Kingston DDR2-533 RAM
- 3 x 160GB Maxtor DiamondMax Plus 9 SATA 7200RPM hard drives
- Enermax 550W power supply
SOFTWARE:
- Slackware 10.1 with custom kernel 2.4.29
- Asterisk 1.0.6
the configurations in zaptel.conf, zapata.conf and extensions.conf were
the same
- astGUIclient suite
Note: Sangoma machine uses wanpipe-beta8a-2.3.3 drivers
The cards compared are the Digium TE405P in T1 mode and the Sangoma A104.
Each server is setup the same with 3 telco T1s connected(one of them
connected on the other end to another Asterisk server) and a channelbank
connected to the fourth T1 port.
The live application used to evaluate performance and gather the stats is
the astGUIclient package with VICIDIAL for outbound dialing.

Here are links to screenshots of our performance monitoring web pages for
each server:

http://astguiclient.sourceforge.net/VDreports/performance_Sangoma_A104.gif
The data was gathered every 5 seconds from both servers.
You can see that even though the Sangoma server ran at slightly higher call
capacity(11% more calls with 4% more talk time), that it still had a
significantly lower average load(27% lower) and peak load(56% lower). The
periodic tests that we have done over the last month confirmed these
results, that all things being equal, the Sangoma server performed 30-50%
more efficiently at doing the same job.
I am currently awaiting a beta test version of the Digium TE406P card(with
the echo-canceller daughterboard) and I am awaiting word from Sangoma on
testing their newly announced A104d card(with on-board echo-canceller) to
see how they both fare in our real-world tests.
