"alacrity", "exigence", "imminence", so on so forth, might refer to specific, different concepts, but fundamentally, that rough corner of semantic space is just loaded with words.
Speed, rapidity, fastness, zippiness; velocity, acceleration, jerk, snap/jounce, crackle, pop; immediacy, urgency; the list goes on.
Anglophones gotta go fast, I guess!!
