Gzip, processing speed: .gz file or just mimicry?

Question

css

Nginx, upon request, gives spa statics - a js file created by webpack and separately css. Maybe someone tested or is there somewhere to read that the browser will process faster at the same connection speed and files:
1. download gz, unzip and process
2. download the mimic file and process it
??

Answer 1

in general, one does not interfere with the other, but if the file is already not large, then gz, on the contrary, will slow down

Answer 2

browser will process faster

what to do faster write a question to the toaster or enable gzip on the webserver and check?
Almost all sites use gz - have you seen the lags?
The processing speed does not change at all, it only affects downloading, unpacking garbage.
