Hi Di-Shi,
In SER, there is at least two parameters that are different for the
development trunk and the upcoming SER 2.0: Debugging and the memory
allocation.
AFAIK, debugging is turned off in RC1,
http://www.iptel.org/ser_2_0_0_release_candidate_1, while the type of
memory allocation has been changed in cvs tagged rel_2_0_0 i.e. upcoming
RC2. Thus, I recommend that you check out rel_2_0_0 from CVS.
There is also a question of which approach you want to take in making
your tests: (1) standard config the way each project "packages" the
server, (2) in some way modified config (turn on/off etc), or (3)
finally an optimized config (which a service provider would do).
I'm sure every large-scale provider (which will be at risk of getting
high bandwidth and CPU levels) have each their own tweaks, for example
the locking mechanism used. I would love to have an iptel.org page that
documents all the various tweaks (if people will share).

All,
This e-mail is follow-up to our previous posting about tests we
performed at TransNexus comparing SER and OpenSER. Our tests
were for wholesale VoIP carriers who want a straightforward, unbiased
comparison of OpenSER and SER. As part of this goal, we purposely
chose the simple implementation of building each software with default
settings.
Folks from the SER community have pointed out to us that building each
platform based on the default configuration does not lead to
an accurate comparison because debug and blacklisting settings for SER
and OpenSER are different and favor the performance results of OpenSER.
Since our goal is to provide users with the most accurate comparison
possible, we are seeking feedback from both communities on what
changes should be made to the SER and OpenSER compile/configuration
options in order to measure an accurate comparison between the two
software platforms.
We are considering re-running the performance test with debug and
blacklisting turned off for both OpenSER and SER based on advice
from folks in the community that this configuration will produce a
more accurate comparison.
Does anyone else have any advice or input to offer before we re-run
the Performance Comparison test?
Thank you,
Di-Shi Sun.
