This command is used to test the performance of cryptographic algorithms.
specifying an engine (by its unique id string) will cause speed to attempt to obtain a functional reference to the specified engine, thus initialising it if needed. The engine will then be set as the default for all available algorithms.
[zero or more test algorithms]
If any options are given, speed tests those algorithms, otherwise all of the above are tested.
