In this paper, adaptive scheduling based on dynamic priorities and imprecise computation is used in web servers. The goal is to keep proportional differentiation services. An approach with admission control has its properties of controllability and predictability evaluated. Another contribution is to show how to use and implement this approach in Apache web servers.Neste artigo, técnicas de escalonamento adaptativo com prioridades dinâmicas e computação imprecisa são empregadas em servidores web. O principal objetivo é manter diferenciação de serviços proporcional. Um controle de admissão é adicionado à abordagem e suas propriedades de controlabilidade e previsibilidade são avaliadas. Outra contribuição do artigo é o de mostrar como implementar essas abordagens utilizando Apache.
