Eu ia postar isso no ServerFault originalmente, mas achei que poderia ser um lugar melhor. Deixe-me saber se você acha que existe um lugar melhor para postar essa pergunta.
Eu tenho um aplicativo de espaço de usuário que executa a rede por meio da API do Java NIO (também conhecido como epoll no Linux) Para fins de demonstração e diagnóstico, eu tenho um utilitário de teste de linha. É basicamente a mesma coisa que iperf .
Algumas informações sobre o ambiente e como o teste é executado.
- Ubuntu 16.04 Desktop atualizado hoje (4.4.0-34-generic)
- o saldo está fora
- Receptor Intel X504T1 10GbE (ixgbe) < - > Remetente Solarflare 10GbE (sfc)
- Usa 10, 000 soquetes TCP
- Sockets usam as configurações padrão do SO
- O buffer de leitura do espaço do usuário é de 32 KB
- a leitura não ocorre mais que 40hz
O teste de linha consiste em um único cliente que transmite o máximo de informações possível sobre os soquetes TCP.
- cada read () por soquete pode ser chamado mais de uma vez para obter até 98KB por hz (o buffer de 32KB teria que ser lido 3 vezes para atingir o limite máximo)
- Isso significa que em 40hz e no teto de 98KB que read () pode ser chamado até 120 vezes por segundo por conexão; lendo um total de 3, 840KB.
- O Line tester mostra que read () é chamado de um total de cerca de 110.000 vezes por segundo.
O teste de linha saturará totalmente o adaptador 10GbE facilmente usando cerca de 8% softirq

Agora, vamos aplicar o controle de taxa ao leitor de soquete.
- O controle da taxa de entrada está definido como 50 KB por conexão
- Que é cerca de 500MB / s, pois temos 10, 000 conexões
O controle de taxa - define a frequência de leitura como 5 Hz, abaixo dos 40 Hz do exemplo anterior.
A frequência do - rate control não está alinhada, o que significa que nem todas as conexões funcionam usando a mesma referência inicial, no entanto, todas são controladas por um único clock.
- o relógio é 40hz; significando que existem 40 oportunidades para que leituras programadas de controle de taxa ocorram.
- durante cada uma dessas leituras de controle de taxa de 5 Hz, o soquete só pode ler até 10 KB. Então, 5 vezes por segundo, ele lê 10 KB do buffer de soquete.
- O Line tester mostra que read () é chamado de um total de cerca de 47, 000 vezes por segundo.
A quantidade de softirq salta de 8% para 50-65%; o número de interrupções quase triplicou e há 26-58 milhões de interrupções de RES (por núcleo) em comparação com 1-7 milhões antes.
