This article will explain in detail about Apache and nginx performance comparison, the quality of the article content is high, so Xiaobian share for everyone to make a reference, I hope you have a certain understanding of related knowledge after reading this article.

What is Apache?

Apache is the number one Web server software in the world. It can run on almost all widely used computer platforms and is one of the most popular Web server-side software due to its cross-platform and security. It is fast, reliable, and extensible with simple APIs to compile interpreters such as Perl/Python into the server.

What is nginx?

Nginx is a lightweight Web server/reverse proxy server and email (IMAP/POP3) proxy server distributed under the BSD-like protocol. It is characterized by less memory and strong concurrency capability. In fact, nginx's concurrency capability does perform well in web servers of the same type. Most websites in mainland China use nginx.

Apache or nginx, which is better?

Nginx has higher performance than Apache.

Reason:

Nginx itself is positioned as a lightweight webserver, with advanced functionality dependent on configuration and load module build. Apache itself is powerful, and its design is also to pursue strong stability.

The core reason is the way the two network IO processing: nginx is asynchronous non-blocking, while apache is synchronous blocking, which is also the reason for ensuring the high performance of nginx and the high stability of apache.

Nginx uses the latest epoll (Linux 2.6 kernel) and kqueue (freebsd) network I/O models, while Apache uses the traditional select model.

At present, Squid and Memcached, which can withstand high concurrent access under Linux, adopt epoll network I/O model.

To handle a large number of reads and writes for connections, Apache's select network I/O model is very inefficient.

The performance comparison between Apache and nginx is shared here. I hope the above content can be of some help to everyone and learn more. If you think the article is good, you can share it so that more people can see it.
