Network Testing
From GridPP Wiki
iperf
To benchmark your network before doing the transfer test an iperf instance is running at Glasgow.
Download the source ./configure and make all. You do not have to install it just pick the binary that is under src.
./iperf -c mon3-gla.scotgrid.ac.uk -p 27890
will test with one tcp stream. Ideally you should try with the number of streams specified for the grid-ftp
./iperf -c mon3-gla.scotgrid.ac.uk -p 27890 -P 10
