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@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 ?
Memory usage looks good, I noticed on my laptop with Linux with Pentium M 1,6GHz that having something like 200 channels connected makes very big CPU usage, but what to expect if every channel was connected to one channel.
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) ?
Anthony here describes that there is one thread for channel, so don't expect it will change.
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.
The same as above. I don't know XP so well, but if it only has problems with many threads for one application then consider running multiple FS instances on one machine.
