[asterisk-users] What's the smallest, lightest Asterisk you can build? Does size even matter?

For most modules there isn't a big point to disabling them as there
isn't an lot of ongoing CPU activity for a module not being used.
That being said, there are some things you can disable that can
improve your performance, but they're going to be application
dependent.  I believe that disabling CDRs, for example, can make a big
difference on heavily loaded systems and some people don't use them.
CDRs take some amount of work at the end to stitch together the notion
of a call from the various call related events that occur.  HEP also
is a big offender.  CELs and AMI can also make some difference when
disabled, but nothing on the order of CDRs and HEP.

Hope that helps!
