OTRS com NGINX ou Apache?

É sabido de todos que um servidor web com NGINX comparado com um Apache mostra um desempenho melhor em diversas aplicações, em especial com PHP, claro, isso não é um dogma, mas quando pensamos em rapidez e performance devemos começar com o NGINX.

Embora a documentação oficial do OTRS não mencione o NGINX é possível configura-lo e usa-lo. Mas e com relação a performance? O NGINX também se mostra superior com a aplicação OTRS?

A resposta curta é NÃO. Pelos testes que fiz, no mesmo servidor, com o mesmo banco de dados e com configurações similares o OTRS fica de 2 a 3 vezes mais lento rodando com o NGINX.

Definitivamente, o OTRS é mais rápido com o Apache.
