Introducing PHP7+Swoole/Nginx/Golang performance comparison

Recommended (free): PHP7

QPS comparison

Use the apache bench tool to perform stress testing on Nginx static pages, Golang Http programs, and PHP7 Swoole Http programs. In the benchmark test of 1 million concurrent HTTP requests on the same machine, the QPS comparison is as follows:

Note: In the test of Nginx-1.9.9, access_log has been turned off and open_file_cache is enabled to cache static files into memory
