 Under CPython expect it to be about 50x slower.
-I think these results are quite good for pure-Python package. For example,
-under PyPy it has faster lookups and uses 2.5x less memory than `marisa-trie`_
-under Python 3.2 (`marisa-trie`_ and `DAWG`_ are currently much
-slower/doesn't work under PyPy).
-It is several times slower under PyPy than Cython-based `DAWG`_ under CPython
-though, so `DAWG`_ + CPython > DAWG-Python + PyPy.
 Memory consumption of DAWG-Python should be the same as of `DAWG`_.
