At its peak i think (based on googling) the nazis killed about 14,000 per day, which would put it in a similar ball park on a per-day basis. However they kept up the level of killing and didn't stop after just a few days.

that's because they weren't shooting crowds already assembled in the streets and going into hospitals nationwide to find the injured. Nazi Germany was aiming to maintain plausible deniability in the concentration camps for as long as possible, while parallel competing plans for what to do with the population were being explored and failing. (there were other solutions before and alonside the final solution)
