 The ``send`` and ``validate_utf8`` methods are very slow in pure Python.
 You can disable UTF8 validation in this library (and receive a
 performance enhancement) with the ``skip_utf8_validation`` parameter.
-If you want to get better performance, please install both numpy and
-wsaccel, and import them into your project files - these external
-libraries will automatically be used when available. wsaccel
-doubles the speed of UTF8 validation while both numpy and wsaccel
-offer a minor performance boost when masking the payload data as
-part of the ``send`` process.
+If you want to get better performance, install wsaccel. While
