[Freeswitch-users] Load testing and thread use

[Richard Lamkin]

Dear All,

 

I am testing FS as a call queuing server.   

 

My test set up is as follows; 

Two Windows XP (SP3) Pc's  with 1.0.3 installed out of the box.  [
Before anyone says use Linux I need to use windows for a specific
reason]

 

I have a single gateway [fsb1500] on FS-1 configured to register with
FS-2 [extn 1500].  

 

I then use the following CLI command to create a call from FS1[5900] to
FS2[5900]

 "bgapi originate
sofia/gateway/fsb1500/5900 at richardl-5013-2.mettonigroup.com 5900"

 

This happily connects FS1[5900] to FS2[5900] .  Codec set to G711a.

I have one hardphone on FS2 with a call connected to 5900 to allow me to
listen to MOH.

 

I have been monitoring the system resources used by FS and have observed
that for each new call a new thread is created.  

I have pushed well over 200 calls from FS-1 into FS2.  

All goes well with the CPU usage by FS (<25%) until 150 concurrent calls
when it starts to climb rapidly and at 175 (~50%). 

One good thing is that memory usage is reasonable with 90MB for 150
calls.

 

My questions are;

Q1 - Is my test reasonable ?

 

Q2 - Windows XP is not that happy with large numbers of thread per app.
Is there a way to configure FS to use fewer threads; instead of using
1/call can it be configured  to use to 1/(n calls) ?

 

Q3 - If there's  not a way to configure FS to combine threads would it
be reasonable to consider modifying the FS code to allow the combining
of  threads or would this be a mammoth task.

 

Regards

 

Richard Lamkin
