Re: download rate to slow tith 1000BaseT

I recommend analysing the problem in stages, and you have done this already. Do 
not start with testing ssh/scp because it virtualises the network connection 
and older versions of ssh have a lot of significant performance problems. 

1) Run a network benchmarking tool like ttcp or iperf. You have done this.

2) Run ftp, and make sure the file being written is /dev/null. This tests how 
fast one end of the ftp connection can get the data off the disk and on to the 
network.

3) Run ftp, and write the file to disk. This tests how fast you can write to 
the disk from the network. I expect that ftp isn't very sophisticated and while 
it is writing to the disk, it won't be reading from the network.

4) Run scp with /dev/null as your destination.

5) Run scp as normal. 

Cheers,
