Here's an interesting graph that shows the performance
differences between the various Python runtime strategies I've
tried - this pertains only to the project's critical section, not
the project as a whole; lower durations are better:
A note about performance:
- 32 bit:
- 64 bit:

- For your first fullsave of a given filesystem, pypy is probably fastest, because it can chunk up blocks rapidly. This
is a CPU-intensive task, and Pypy shines on CPU-heavy workloads.
- For subsequent fullsaves, I like CPython 3., because they have a built-in lzma module, and the task is more I/O
heavy and CPU-light. For I/O-heavy loads, CPython tends to be faster than Pypy.
