Is it me or homebrew became slower recently?

I recall that some commands where much faster. It takes on average 2.5 seconds to do brew search.

$ time brew search mpv ==> Formulae mpv

==> Casks mpv brew search mpv 2.34s user 0.59s system 67% cpu 4.348 total

This is not autoupdate — this is with set HOMEBREW_AUTO_UPDATE_SECS to 14400.
