 As can be seen from the sizes, both lxml.etree and cElementTree are
-rather memory friendly compared to the pure Python libraries
-ElementTree and (especially) minidom.  Comparing to older CPython
+rather memory friendly and fast.  Comparing to older CPython
 versions, the memory footprint of the minidom library was considerably
 reduced in CPython 3.3, by about a factor of 4 in this case.
