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 
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).
