Comparação de Configuração de Servidor Rails

Esse é o início de um teste para chegarmos um dia em uma configuração legal de uma aplicação feita em Ruby On Rails.

Atualmente estamos rodando a aplicação Criamos utilizando FAST CGI , isso significa dizer que para cada requisição feita pelo navegador ele carrega lalalala descrver melhor isso.

Os testes foram realizados num mesmo computador com a configuração descrita aqui e com um link de 1MB da velox.

Rodando com a configuração descrita acima ficamos com o seguinte resultado acessando a página inicial do sistema utilizando a ferramenta ab (do pacote apache-utils). Realizando X requisições.

Configuração 1

A primeira configuração utilizada para os teste foi:

Obtemos o seguinte resultado:

  • X = 1
