Hi David,

Yes, we have done more than 1000 concurrent calls. Here are a few things we needed to do:

1) Add the following to /etc/security/limits.conf

*         hard    nofile      65536

*         soft    nofile      65536

root      hard    nofile      65536

root      soft    nofile      65536

freeswitch hard stack 10240

freeswitch soft stack 244

freeswitch hard nproc unlimited

freeswitch soft nproc unlimited

2) Add the followings to /etc/init.d/freeswitch

        ulimit -c unlimited

        ulimit -d unlimited

        ulimit -f unlimited

        ulimit -i unlimited

        ulimit -n 999999

        ulimit -q unlimited

        ulimit -u unlimited

        ulimit -v unlimited

        ulimit -x unlimited

        ulimit -s 240

        ulimit -l unlimited

3) Set rtp-timer-name to none and rtp-timeout-sec to zero in your sip profile.

Regards,

Ali Pey

Have you tried spreading the calls over more than 1 SIP profile?  Each SIP profile gets its own thread.

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
