  • Added profile module
  • Annotated task launch to use the profiler
  • Added async_profile script to make pretty graphs

The profiler requires the package graphviz and is used as follows:

$ fab local # (with debug=True)
$ python async_profile.py logs/node-0.log
$ dot -Tpng parentgraph.dot > parentgraph.png
