Quick google yields very good examples in huge improvements on a single algorithm level: ▶ this video Easy to imagine how even smaller improvements across 10-100 steps of data processing, can become even better.

Also keep in mind that there’s people out there that will take your code and make it 40.363.757.265% more efficient (perhaps not in this case) ▶ this video
