I am using G711 codec. There are no firewalls. It is a small, nearly self-contained network of the sipp machine, a switch, and the FS machine. The links show to be 1G and full duplex. The calls come in at around 2 per second, so I think the single Sofia profile thread for the signaling should be acceptable. Do you agree?

Also, is this all within your LAN? No firewalls/filters? Are you sure you are linking at 1Gbps, full duplex?

Hi,
I would like to put 500 - 1000 calls into a FS system.
I have a Dell R900 server with these properties:
8 processors at 2.40GHz
8GB RAM Gigabit ethernet
I use sipp to send RTP streams.
I use the FS settings recommended here: https://wiki.freeswitch.org/wiki/Performance_testing_and_configurations including the in-memory core.db.
I also have used the "-rp" and "-nosql" settings on the FS command-line, and also used the "chrt" command to increase the priority to real-time.
In all cases, at around 300 concurrent calls, the RTP inter-packet delay becomes unacceptably high. The voice quality is severely impacted.
During the test, the CPU is not overloaded. It is using only about 1.5 of the 8 processors.
Are these results expected?
Has anyone gone higher than 300 concurrent calls?
Is there anything else that I can do with configuration to improve throughput?
Thanks, David
