Bootup a machine with a broadcom 5762 NIC (ie. HP DeskElite 705) using a Ubuntu/Kubunu Live CD 14.04-15.04. 2. from another machine: start 5 sessions, repetitively copy (scp with public key authentication) a 70 meg file back and forth to the tg3 machine in each session. (not sure if this is necessary) 3. create a 1GB file on the tg3 machine, with something like dd if=/dev/urandom of=/my/test/file bs=1024 count=$((1024*1000)) 4. from another machine: repetitively scp copy that 1GB file from the tg3 machine. This can be done with something like: while [ 0 ]; do scp -i /my/scp/private.key u...@ip.of.tg3:/my/test/file /tmp done; Networking will mostly goes offline in about 10-30 minutes.
