download rate to slow tith 1000BaseT

[Philip Miller <sighoya%gmail.com@localhost>]

If I upload a large binary file in netbsd, then the speed is around 
40MB/s, which is normal. But by Downloading a large binary file, the 
download speed is around 11MB/s, which is to few.
My network card configuration:
-bash-4.2$ ifconfig nfe0
nfe0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        address: 00:25:22:8a:a9:5c
