<div class="moz-cite-prefix">Hello Andre.<br>
<br>
Solving performance problems is always hard , but a few points to
keep in mind :<br>
<br>
To my knowledge FS is pretty much a linux software , it works on
windows by that i doesn't means it performs on windows ( please
correct me if i'm wrong)<br>
The native DB for FS is Postgresql ( this should make you oracle
admin more happy :) ).<br>
<br>
Try this :<br>
Linux Server Realtime Kernel + Last FS Stable + Postgresql ( tune
it well).<br>
Take care with ulimit on linux , its needed for the extra punch of
performance<br>
Check if your "performance test" is real if you are pointing to
1500CPS for a two minute call you will have 180k calls before the
first call gets disconnected, if you are also testing RTP that
means 180k * 2 ports needed , The Kernel will start to complaining
and you will run out of ports you will also run out of FD probably
before you run out of ports on a not tuned linux install.<br>
If the DB is on the same server it will also stall since the FD
will not be present for new connections to the back end.<br>
<br>
In terms of BW you will exceed 230000 kb/s add a few more kb/s for
the DB ( Not a problem here i think)<br>
<br>
Another thing , no sip server ( please include all the nice names
here like B2BUA , etc ) should ever queue anything.<br>
I have never read the code that handles this on FS but the way i
would do it should be something like : can we sustain the load ?
No in that case send 503 else proceed.<br>
This is done in freeswitch by this var<br>

<br>
A more general approach:<br>
In SIp Servers you will generally ( if not running cpu intensive
tasks, trancoding , tone detection , etc ), consume all the ram ,
Network IO ,than the cpu.<br>
For the guys that plan something big you should take a look at
this :<br>

Not by The NIC itself but because of this :<br>

<br>
Without more data i don't think we can help , above all
performance testing is a dark art you just need to keep on trying
different things and above all have some type of monitor tool to
understand what exactly is holding you up , maybe its no FS...<br>
<br>
Also 1500CPS is something seen in carrier operations generally
with a named SBC in front , keep in mind that FS is a great
software but it doesn't hold against SBC's that use special
processors like ASIC to perform transcoding , sip parsing , tone
detection ,etc etc<br>

<p class="MsoNormal">Hi, I am testing out my FreeSWITCH 1.2.14
64 bit windows 8.1 on my Alienware Laptop with a very fast SSD
and I7 processor with 8 GB DDR3 Ram.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have been using a pjsip test tool to test
FreeSWITCH to see how it performs. Tell me if I’m wrong here,
I believe if I sent “too many” calls to FreeSWITCH that it
queues up the calls and sooner or later uses all the memory on
my PC then just stops working. I do have the CPS sent to 1500
for testing but I never hit that high, I hit about 200 CPS.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The CDRs that save to my database show it
takes about 8 seconds from start time to end time. It does
start out only taking milliseconds then it progresses to the 8
second mark. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The calls are just going to FreeSWITCH then
I’m sending back a 503.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have every mod turned off, logging set to
0, Core db going to a SQL Server and I even set FreeSWITCH to
real time.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can anyone give me advise on what I can do
to get better performance? I’ve also tested it out on my real
server but in about 3 minutes of 50 cps FreeSWITCH uses up 3gb
of memory and stops responding.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m at a loss here on what else to do.<o:p></o:p></p>
