Estava testando minhas velocidades entre meu laptop Ubuntu Server 14.04 e Windows 8.1. Recentemente, o servidor Ubuntu teve uma nova placa de 10/100/1000 gigabit instalada, funcionando perfeitamente e mostrando 10/100/100 em ifconfig.
Então eu fiz um teste iperf através do roteador 10/100 e foi 86Mbits / s - ok, bom o suficiente.
Então eu conectei diretamente ao servidor do laptop usando um cabo, ambos os cartões ethenet gigabit configurados e .... mesmo resultado .... 86Mbits / s.
Estamos olhando para alguma forma de configuração de software necessária aqui ou estou fazendo algo descaradamente errado?

Qual é a diferença entre tamanho e capacidade? O servidor deve ter 1Gbits para tamanho e capacidade?
