On host 'abc' I run:
iperf -s -w 256k
On host 'xyz' I run:
iperf -c -w 256k
And I get 900Mb. When I reverse the commands, making 'abc' the client, I get 200Mb. This means that abc's upload speed maxes at 200Mb.
There are no devices between these hosts, and they have no firewalls or rate limiting of any kind in place. They both have 1Gb ethernet ports.
Running iftop on abc shows very little Tx activity (so there isn't anything being uploaded). These are Debian hosts. Any ideas?
