I would think running regression should be more demanding on the potato then decompressing ZIP file.

hmm good point, can you draft up an architecture plan using multiple microservices and redundancy via a kubernetes cluster and have it on my desk by Monday please.

What machine could anyone be running an analysis on where unzip is a limiting factor?

you heard them, a literal potato from the ground.

even a big old russet only has, what, like 32 bites?

I mean there are some potatoes that take more then four bytes to eat, but they are rare.

For some, if you slice them, you might even end up with only 16 bits.
