.. note::
- By default, :meth:`timeit` temporarily turns off garbage collection during the
- timing. The advantage of this approach is that it makes independent timings
- more comparable. This disadvantage is that GC may be an important component of
- the performance of the function being measured. If so, GC can be re-enabled as
- the first statement in the *setup* string. For example::
