When you mount via rclone, are requests made via the mount parallel or sequential?

Lets say I have to do 10 list commands on the mounted file system. If I do 10 ls commands sequentially, then 10 ls commands in parallel can I expect the 10 ls's done in parallel to be 10x faster then the 10 ls done sequentially?

Rclone will run the ls commands in parallel I think (it depends slightly on FUSE which is complicated and I don't fully understand!).

I don't think you'll find a constant answer on that as it really depends.

It depends on how many cores on the system.
It depends on how the fuse was compiled for that system.

Most of the time, I'd expect 10 parallel to return faster than 10 sequentially.
