As I can see, you get better and better with openser,
maybe you can get some training so you will be able to configure and tune it properly to
fit your needs and get the appropriate results (googling will reveal some doing trainings
for openser). So which are right, these ones, the previous ones or the next testing
results? You tested something, which (I suppose) you are very familiar with (ser), against
something that you do not know properly to configure. There are some internals that differ
a lot and may have quite a lot of performance impact.
Just after you sent this mail, I have seen a commit to usrloc which saves some problems I
pointed in my previous email in this thread (so, yes, we are concerned about performance,
and see you need to catch up now in some directions). The difference is now that ser's
usrloc hash table size is by default 2^14 (16384) while in openser is 2^9 (512). So I
guess some tests you can do now will be faster for ser, but to change the hash value in
ser you have to re-compile, as opposite to openser where you can do it via module
parameter.
So please, try to make sure that the corresponding parameters have same values, from
number of processes, to memory, hash tables sizes, and so on ... for future tests. If you
are not able to do fair tests, it is better to leave it for some impartial entities. With
the description of your tests a lot of parameters and variables are hidden, and do not
reflect the real capacity of the applications (I can say it now at least for openser).
And just to remember, as proved, you got very good performances but wrong processing. I
will ask you and users: do you prefer to have *high performances* tied to *invalid
processing* of the requests?
Well, maybe for some folks it is a 'proud' to say: *ser offers very fast _invalid_
functionalities* or "ser can scale to millions of _offline_ users*.
You owe to say to the users that the performances were obtained with a *buggy SIP
transaction processing*, and correct the web pages posted at the link below.
Actually I replied to this mail because of some accuses that 'we spread the rumor
"ser is dead"'. Nowhere you can find such statement from our side. After
some investigations proved that the phrase in charge is:
"Soon after, /iptelorg.com Gmbh/ was sold to /Tekelec/, which had no intention to
continue the development of the public project."
from oepnser history
(
)p;Itemid=61).
This is quite different than "ser is dead", and many of you know the statement
made in "openser history" is true. I cannot name some private channels I have,
but there are publicly spoken ones. I paste from
:
<snip>
Christian says that he was surprised at the continued development of
SER after speaking with people from Tekelec, as they mentioned that
they were not as interested in continuing SER as an open source
project and were more interested in integrating SER into their IMS
offerings. He asks about the future of SER as an open source
project. Jiri feels that there should be no issues, and the main
contributors are still making contributions. He's hesitant to speak on
the behalf of the company, but feels that based on past performance
nothing should be changing.
</snip>
I would polite ask those persons not to twist the phrases without giving good proof.
Users can see now who and how tries to hoke up the reality.
Cheers,
Daniel

I'm sorry to nip in, but I tried to rerun the
tests again and add more
info into output as requested and add stable ser and CVS openser.
I know that this test doesn't conform much to real life (for example
generated callid/branch/tags differs only in a number, etc) but it can
give at least an image about simple stateful forward.
So, if anybody is interested:
http://www.iptel.org/~vku/performance/tm.serXopenser.correct/
I tried the same once more with less iterations because there were some
errors in log from openser speaking about low memory (I used -m to
specify shared mem size but with 768M it still said errors, might be a
memleak or did I anything wrong?). With 1M iterations it was without
errors:

P.S. I have forgotten - SIPP was "Sipp v1.1, version 20060829, built Sep
5 2006, 15:07:25", I'm attaching simple patch which I have used.

hardware, without extra configuration overhead, just plug and play. And that is stable
version of OpenSER since July this year (btw, for those who keep saying that OpenSER does
not focus on stability, just check the CVS and see the number of bugs encountered with
this release, maybe you can change your opinion), and you can have a safe environment
distributed geographically where each hardware can undertake the traffic from the others
on the fly. With single box crashing because of different independent reasons (hardware
failure, power outages ...) you get no service ... with three boxes you can serve huge
number of active subscribers in peak hours and have failover support, so service
availability 100%. I am sure most of the people look now how to build reliable platforms
that scale very easy and can be distributed around the world, with a bunch of useful
features -- simple first line replacement is not the business case for VoIP anymore.

Daniel stated that OpenSER now performs a whole much better while loading users from

just really curious to see how both servers perform, that's all. Even though I must
maintain my SER, I kinda like OpenSER's faster releases and developers'
responsiveness (that I shamelessly exploit for the common code left there :-), which is
pretty much nonexistent with iptel (at least this is the general belief here at OpenSER).
But about this I'll probably have to fight on SER's mailing list. I still wish
that one day I won't have to compare features; heck, NetSER and FreeSER are still
available ;-). WL.

After all, there are plenty of UA-level stacks out there. At least now that both projects
get to have stable releases after forking and some core functionality remained shared. I
wonder what "unbiased" organization will take up the challenge. :-)
