I have an FTP server which I'm accessing through another machine in the LAN, both machines are connected to a 300 Mbit/s router and both machines have a 10/100/1000 Mbit NIC.
With this setup I expect to see speeds of around 40MB/s but actually what I see is 10MB/s (which is my internet connection's speed 80Mbit/s).
Is my understanding wrong or what is happening here?
I can confirm I'm not going through the internet because I'm using LAN addresses to realize the communication.
EDIT: I notice that my LAN connection adapter is showing a speed of 100 Mbit/s (in windows network and sharing section), why is that? If I need a giga router in order to achieve speeds higher than 100 mbit then what's the point of 150 300 450 mbit routers at all?
