Passenger Nginx가 동시 요청을 처리하는 방법을 이해하려고했습니다. 페이지를 새로 고침하고 프로덕션 로그를 보았습니다. 각 페이지는 서버에 여러 개의 동시 아약스 요청을 보냅니다. '상태', 'mentorship_templates'및 '멘토십'이라고하는 값 비싼 db 쿼리를 필요로하는 퀘스트가 있습니다. 로그를 분석하여 두 가지 시도가 나에게 다른 결과를 준 것처럼 보입니다. 여기에 내가 요청이 동시에 처리 것을 볼 수 있습니다승객 Nginx가 동시 요청을 처리하는 방법

이 보이는합니다. 그것은 나를 혼란스럽게한다!
프로덕션 서버로 Passenger Nginx를 사용하고 데이터베이스가 mysql 인 레일 앱입니다. 나는 이것이 무엇에 대한 좋은 설명인지 궁금하다. 여객 Nginx는 동시 요청을 어떻게 처리합니까?
Passenger의 한 프로세스에서 Rails 앱 인스턴스입니까? –
opensource 버전에 맞습니다. 1 프로세스는 1 Rails 앱입니다. –
