Finding Something To Do

=======================

Ad-hoc performance work can also be done. One useful tool is the 'evil' debug

flag. For instance running ``bzr -Devil commit -m "test"`` will log a backtrace

to the bzr log file for every method call which triggers a slow or non-scalable

part of the bzr library. So checking that a given command with ``-Devil`` has

no backtraces logged to the log file is a good way to find problem function

calls that might be nested deep in the code base.
