<p class=MsoNormal style='margin-bottom:12.0pt'>The core philosophy of the
entire design is based on a single thread per channel.<br>
There is no way to avoid this.<br>
<br>
What are the specs of your machines? <br>
DId you try using the 2003 server instead of XP (a home version meant for
single users)<br>
<br>
We have little feedback on performance on win32 (good or bad) but we do have
many people using it.<br>
<br>
Did you do any more extensive profiling to see what is using the most cpu (look
for process explorer)<br>

<p><span lang=EN-GB>Dear All,<o:p></o:p></span></p>
<p><span lang=EN-GB> <o:p></o:p></span></p>
<p><span lang=EN-GB>I am testing FS as a call queuing server. <o:p></o:p></span></p>
<p><span lang=EN-GB> <o:p></o:p></span></p>
<p><span lang=EN-GB>My test set up is as follows; <o:p></o:p></span></p>
<p><span lang=EN-GB>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]<o:p></o:p></span></p>
<p><span lang=EN-GB> <o:p></o:p></span></p>
<p><span lang=EN-GB>I have a single gateway [fsb1500] on FS-1 configured to
register with FS-2 [extn 1500]. <o:p></o:p></span></p>
<p><span lang=EN-GB> <o:p></o:p></span></p>
<p><span lang=EN-GB>I then use the following CLI command to create a call from
FS1[5900] to FS2[5900]<o:p></o:p></span></p>
<p><span lang=EN-GB> “bgapi originate sofia/gateway/fsb1500/<a
href="mailto:5900@richardl-5013-2.mettonigroup.com" target="_blank">5900@richardl-5013-2.mettonigroup.com</a>
5900”<o:p></o:p></span></p>
<p><span lang=EN-GB> <o:p></o:p></span></p>
<p><span lang=EN-GB>This happily connects FS1[5900] to FS2[5900] . Codec
set to G711a.<o:p></o:p></span></p>
<p><span lang=EN-GB>I have one hardphone on FS2 with a call connected to 5900
to allow me to listen to MOH.<o:p></o:p></span></p>
<p><span lang=EN-GB> <o:p></o:p></span></p>
<p><span lang=EN-GB>I have been monitoring the system resources used by FS and
have observed that for each new call a new thread is created. <o:p></o:p></span></p>
<p><span lang=EN-GB>I have pushed well over 200 calls from FS-1 into FS2.
<o:p></o:p></span></p>
<p><span lang=EN-GB>All goes well with the CPU usage by FS (<25%) until 150
concurrent calls when it starts to climb rapidly and at 175 (~50%). <o:p></o:p></span></p>
<p><span lang=EN-GB>One good thing is that memory usage is reasonable with 90MB
for 150 calls.<o:p></o:p></span></p>
<p><span lang=EN-GB> <o:p></o:p></span></p>
<p><span lang=EN-GB>My questions are;<o:p></o:p></span></p>
<p><span lang=EN-GB>Q1 – Is my test reasonable ?<o:p></o:p></span></p>
<p><span lang=EN-GB> <o:p></o:p></span></p>
<p><span lang=EN-GB>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) ?<o:p></o:p></span></p>
<p><span lang=EN-GB> <o:p></o:p></span></p>
<p><span lang=EN-GB>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.<o:p></o:p></span></p>
<p><span lang=EN-GB> <o:p></o:p></span></p>
<p><span lang=EN-GB>Regards<o:p></o:p></span></p>
