I wanted to transfer files between two mac computers. The network is wireless-N and both computers have wireless-N modules in them.
The problem is that when I transfer files between them, via file sharing (afp) the network speed caps at 2 megabytes/sec. Just downloading files from the internet I can get faster speeds, so this isn't a constriction of my wifi bandwidth, it appears to be a constriction of the protocol being used.
My wifi-n is set to 130mbits, so I should see real world transfer speeds around 12-16 megabytes/sec
I did this command on both computers
sudo sysctl -w net.inet.tcp.delayed_ack=0 which is supposed to lower tcp overhead, but this did not affect it.
How can I get the speed I am expecting?
