Tenho um plano de teste JMeter com um sampler fictício e um Constant Throughput Timer adicionado como seu filho. Quero atingir uma meta de 10 TPS, então defino o throughput para 600 amostras por minuto, Usuários - 10. No entanto, após executar o teste, esperava que ele atingisse 10 TPS, mas não está funcionando como esperado. Alguém pode me ajudar a identificar o que posso estar fazendo errado?

O tempo médio de resposta é de 276 milissegundos, o que significa que um usuário pode fazer 3,62 solicitações por segundo, 10 usuários farão 36 solicitações por segundo.
Se você precisar de 600 solicitações por segundo, será necessário aumentar o número para 166+
Você também pode dar uma olhada na combinação Throughput Shaping Timer e Concurrency Thread Group , eles podem ser conectados através da função Feedback , dessa forma o JMeter será capaz de iniciar threads extras se a quantidade atual não for suficiente para atingir o throughput desejado.
