means Moving, operating, or capable of operating at a very fast rate or velocity.
from A transparent compound of two old English-rooted words. 'High' comes from Old English 'hēah,' meaning lofty or great in degree — the same word that lets us speak of high prices and high hopes, not just tall mountains. 'Speed' descends from Old English 'spēd,' which originally meant success, prosperity, or good fortune (to do something 'with speed' was to do it luckily and well) — a cousin of the verb in the old blessing 'God speed you.' Only later did 'speed' narrow to mean swiftness, the pace at which fortunate things were thought to arrive. So 'high speed' literally stacks 'great' atop 'swift success' — a phrase that has been racing ahead ever since machinery gave it something to measure.
