On my decently fast home connection, Emacs takes 4.5s-5s to download that file 
using the form you posted, and wget takes 1.4s-2s to download the same file:

(benchmark-run 1 (url-retrieve-synchronously 
"https://ftp.gnu.org/gnu/emacs/emacs-27.2.tar.xz";))
⇒ (4.875848555 13 3.7572300619999623)

(benchmark-run 1 (shell-command-to-string "wget 
https://ftp.gnu.org/gnu/emacs/emacs-27.2.tar.xz";))
⇒ (1.5106374 0 0.0)
