IIUC, when the TTL hasn't been exceeded, then the file from the file
system is served without contacting the remote server at all.  So in
the best case, you only ‘round-trip’ to the disk instead of the HTTP
server.  So I think there's some potential benefits to be had here.

That assumes a sufficiently large TTL though.
