6 speed - test library performance
40 This command is used to test the performance of cryptographic algorithms.
48 specifying an engine (by its unique B<id> string) will cause B<speed>
49 to attempt to obtain a functional reference to the specified engine,
50 thus initialising it if needed. The engine will then be set as the default
51 for all available algorithms.
53 =item B<[zero or more test algorithms]>
55 If any options are given, B<speed> tests those algorithms, otherwise all of
