Hi stackers, Recently, I started working on speeding up Rally cli.
What I understand immediately is that I don't understand why it takes 700-800ms to just run "rally version" command and it is impossible hard task to find what takes so much time just by reading the code. I started playing with patching __import__ and make a simple but powerful tool that allows you to trace any imports and get pretty graphs of nested importing with timings: https://github.com/boris-42/profimp So now it's simple to understand what imports take most of time, just by running: profimp "import <lib>" --html Let's optimize OpenStack libs and clients? Best regards, Boris Pavlovic
