Says who? My .gvfs directory is owned by me. See here

The conversion is 8 bits = 1 bite. 12.5 Megabytes = 100 Megabits. The protocol 100BaseT (Fast Ethernet) operates at max 100 Megabits per second (100 Mb/sec or 12.5 MB/s). You can do the calculation yourself here
I have noticed the speed improvement as well, and I was tempted to set up some manual file shares as well, wondering what the consequences would be. Well, you found one of them!
The speed goes from "Dog-Slow" to OK, and perhaps limited by network bandwidth and switchgear. A 100BaseT network is doing well to achieve consistent 18 MB/sec transfers.
If you are using a switched network (no hubs) then all devices have a 1 to 1 conversation end to end. There is no collision domain. The only concern is end to end bandwidth. How many devices are on any segment is only tangentially important.
Remember, it is sharing the network with potentially 254 other devices.
