Introduction

In Nginx scenario tests, the test tool httpress is used. This tool can send multiple types of requests, such as HTTP short connections, HTTP persistent connections, HTTPS short connections, and HTTPS persistent connections. It can be used to test a large number of concurrent web requests. In HTTPS scenarios, encryption and decryption consume a lot of CPU computing capabilities. For HTTPS short connections, connections need to be re-established for each data exchange, which means that RSA encryption and decryption need to be performed for each data transmission. The CPU computing capability determines the processing performance of the server.
