Hello,

The CMakeList.txt of the library doesn't contain default CMAKE_BUILD_TYPE to be
set to Release. Neither this variable is not set in debian/rules file. So the
resulting library is build with no optimization enabled which hits performance
by factor of around 2x.
Setting CMAKE_BUILD_TYPE to None and using the distribution default
C(XX)FLAGS is what debhelper defaults to [1].
In the prometheus-cpp build logs [2] I can see that the "-O2"
optimization flags get applied.
How did you measure the performance degradation?
Thanks,
Gregor
