Test the Nginx performance

Brief introduction

Nginx ("Engine X") is a high-performance HTTP and reverse proxy server, but also a IMAP/POP3/SMTP proxy server;

As a lightweight Web server, with less memory, concurrency and strong advantages, is a high connection to the concurrent scene of Apache good alternatives;

This article mainly introduces Nginx as a Web server, compared to Apache performance advantages;

The next article will introduce the implementation of Nginx as a directional proxy server;

Important Features

Non-blocking: The first phase of disk I/O is non-blocking when data is replicated;

Event-driven: communication mechanism adopts epoll model to support larger concurrent connections;

Master/worker structure: A master process that generates one or more worker processes;
