I'm having an odd problem with the ethernet connection on my Pi. All examples below use wired connections.
Copy file from laptop to Pi sd card (ssh,ftp,samba): 50-60 kb/s
Copy file from Pi sd card to Laptop (same): ~ 2 mb/s
Copy file from Pi sd card to Pi ntfs usb: ~ 4 mb/s
When I copy from Pi sd to Pi usb the CPU maxes out with the ntfs mount process. (as expected) When copying from the laptop to Pi, the CPU doesn't get above 10%. So CPU and disk speed can't be blamed. And the ethernet connection itself seems okay since I can get 2 mb/s on a read.
Does anyone have any idea what might cause my ethernet to be so slow when writing to the Pi?
