Currently py_wheel
+ wheelmaker
uses standard zip compression when producing a wheel. When you're iterating on a wheel target, this can take a huge amount of time for large wheels with native binaries. In our case it takes ~3 minutes just to zip the dev wheel. It would be great if this compression knob was exposed somehow, in our case that time goes down to ~10 seconds if I just change this to zipfile.ZIP_STORED
