I have no idea about boost interprocess, but until somebody more
knowledgeable answers here are some general tips:

   1. see preprocessed file so you can check how much LOC boost
   interprocess adds
   2. ask compiler to print include files, so you can get the idea what
   boost interprocess includes if you do not want to go over boost
   interprocess files manually and look for includes

LOC is not a precise way to check for slowdowns, but it is a good proxy,
for example
g++-13  example.cpp -E  | wc -l
12461
Then you add boost interprocess headers to example, repeat the command and
see how much code was added.
