Using `zip` from FreeBSD base, I created a compressed (-9) .zip file 2MB
containing 24 text files 7MB. The command `unzip -l` takes 0.004s real time
on my PC and 0.014s on my weakest VPS ("CPU 500 MHz").

The `unzip -l` command lists compressed files, doesn't decompress them.
I don't understand why `unzip -l` takes 1m16s to list 20-30 files.
It's definitely not normal.
