Importing pkg_resources has a side-effect of reading all of the metadata for every installed python package. The newer importlib.metadata module can load the metadata for one package at a time, which makes this library load more quickly and improves the startup-time performance of applications that use it such as python-openstackclient. importlib.metadata is part of the python 3.8 standard library and is distributed separately for other versions of python.

OSProfiler -- Library for cross-project profiling
OSProfiler provides a tiny but powerful library that is used by most (soon to be all) OpenStack projects and their python clients. It provides functionality to be able to generate 1 trace per request, that goes through all involved services. This trace can then be extracted and used to build a tree of calls which can be quite handy for a variety of reasons (for example in isolating cross-project performance issues).
