I noticed that opening files via an sshfs mounted remote has gotten
extremely slow (about 10 seconds vs 2 seconds for opening the same
file).
(This bug report unfortunately got no response at the time.)
I tried reading a large .flac file with "cat" on the terminal and with
Emacs over sshfs, and there didn't seem to be any large difference in
time for me (on Debian/bullseye with Emacs 28).
Are you still seeing this issue with more recent versions of Emacs?
