Morphology
at + lightspeed
The phrase combines the locative/measure preposition 'at' with 'lightspeed' (the speed of light), so its meaning 'at a very fast rate' is directly derivable from the constituents. Though metaphorical, the construction follows a regular rate-of-motion pattern and has clear cross‑linguistic parallels (e.g. 'a la velocidad de la luz'), so a B1 learner who knows the parts will understand it.
Etymology
At lightspeed comes from the image of moving as fast as light or at full speed, like a flash you can hardly follow. That's why it means 'very quickly'.
