That's Mbps, with a small b, bits per second. The speed is unimpressive. Using only 2.5 GHz band the maximum rate is about 400 Mbps. The RPi3 is only getting about 1/4 of what it should be able to do but still almost as good as wired 100 BaseT.
On the same WiFi router my Mac gets just over 1,000 Mbps, about as fast as Gigabit Ethernet. Is SSHFS on a Pi3 fast enough? It all runs in user space and the data moves buffer to buffer to buffer. NFS stacks are pretty much no days zero-copy, DMA writes into user space from the kernel. This might matter on a Pi that is also trying to cut metal at the same time. Or maybe not the Pi is quad core. As for network boot. The Pi will do that on it's own. the setup is on the DHCP server and you ned an image file on a TFTP server. Then after it boots there are mount points in /etc/fstab to mount home directories and such via NFS. This is all at least 20+ years old technology.
