[Serusers] How to build in SER modules statically for profiling?

[Jiri Kuthan]

We used to use the static_modules for gprof profiling long time ago succesfully but we haven't
done that for quite a while. I think it would take some code pollishing to make sure it is
workable again. If you do that, please let me know -- I would be keen to learn the results.

However, tools like gprof and Intel Vtune's sampling tool can not show any information about the functions in dynamically loaded modules, such as tm, registrar. So, a possible solution seems to build in these modules into the core statically.
