[Freeswitch-users] FS benchmark test

[Santiago Gimenez Ocano]

We have
been doing tests in order to establish benchmarks. This is the scenario:

 

SIPp -------> FreeSWITCH -----
> Destination

 

SIPp:

SIPp is
using the uac scenario with a delay of 15000ms. 

 

     INVITE ---------->                  

100 <----------         

            180
<----------                  

183 <----------                  

200 <----------  E-RTD1 

            ACK
---------->         

            Pause
[    15.0s]                 

            BYE
---------->         

            200
<----------  

 

FreeSWITCH:

We have
used two different servers:

 

FS1: Virtualized

            Processor:
Xeon @ 3.00GHz

            OS:
Debian  

Kernel version: 2.6.18-6-686

FS version: 1.0

Preemption: disabled

 

            FS2: Not virtualized

                        Processor: Intel Dual
Core @ 3GHz

                        OS: Fedora Linux 9

                        Kernel version: 2.6

                        FS version: 1.0

Preemption: enabled

 

Both
servers are running in no console mode and with ulimits, as http://wiki.freeswitch.org/wiki/Performance_testing_and_configurations
and  http://wiki.freeswitch.org/wiki/Long_term_testing_chevymanjosh
mention.

 

Also, both
servers are using the same dialplan which access to a database via Java Script.
This database receives a query with the destination number and respond with a
list of destination IP. Then the calls is bridged.

 

The
results:

In FS1 we
have had a load average of  4.00, retransmission
and errors with 7 attempts per second and 100 sessions aprox.  

In FS2 we
have had a load average of  4.00, retransmission
and errors with 13 attempts per second and 200 sessions aprox..

 

Conclusion:

We are
worried about this behavior and think about this figures are quite low in comparison
to other experiences that we have seen in Wiki (1000+ calls and 50 attemps/sec)
or articles. 

JS is not
the problem, we are getting the same results using a simple dialplan.

 

<include>

        <context
name="default">

                <extension
name="init" continue="true">

                        <condition
field="destination_number" expression="^(.*)">

                                <action
application="set" data="accountcode2=8888"/>

                                <action
application="set" data="contexto=dp3"/>

                                <action
application="set" data="called=15555555555"/>

                                <action
application="set" data="export_vars=uuid,destination_number,accountcode2,contexto,cal

                                <action
application="bridge" data="sofia/default/1555555555555 at 192.168.1.182"/>

                        </condition>

                </extension>

        </context>

</include>

 

So, all is pointing
in some bad configuration that we are missing.

 

Please, if
you have any idea it would be appreciated.

 

Thanks in
advance
