Origin

Old English spēd (noun), spēdan (verb), from the Germanic base of Old English spōwan 'prosper, succeed', a sense reflected in early usage.

The Germanic root of this Old English word had a basic sense of ‘prosper, succeed’, which still survives in expressions as God speed! and more haste less speed. The link between this and ‘rapidity’ is probably our tendency to equate doing something well with doing it quickly. Speed has been a slang term for amphetamines since the 1960s.
