Instead of seeking in the filesystem you end up seeking in the zip. Why
do you expect it'd be faster?

It's not the cost of starting up an empty Python. It's the cost of
loading the tons of stuff that every app uses.
Trust me, zip files *do* make for much speedier app startup times.
It's been tested many times.

Less stat calls in exchange for seeking in the zip "filesystem" plus
decompression. IWBN if someone shows real numbers...
Decompression time is balanced, probably more than balanced, by shorter
disk reading times. In the last twenty years, cpus have speed up much

that it's spread over less disk blocks.
