Question: is RomoteSubl (through rmate) faster than using sshfs?

Hello, I have been using sshfs to mount remote ssh files/folders, to be used with sublime. Sometimes it's getting show using the sshfs (due to network etc.) - I am wondering if rmate/RemoteSubl has speed advantage over using sshfs, or the performance is similar as both are through ssh/tunnels?

Another related question: is whether rmate can open remote folders?  

Thanks a lot!
