This is a creation in Article, where the information may have evolved or changed. Nginx is very good at dealing with high concurrency, and go is a new era of Internet language designed to achieve high concurrency at the beginning of the design. The Ngx_lua is handled by Nginx to handle network events and uses a co-process to implement non-blocking for high concurrency. The Go language level provides a non-blocking API, which also uses a thread to provide high concurrency processing. Let's test

Recently, the partner wants to perform a performance test on our application server. The basis of the test is the partner's original business system with huge functions and complex structures, the purpose is to check whether the application server can meet the needs of the business system and make a general evaluation of the application server. Due to limited hardware resources, the hardware server is configured with two quad-core Zhiqiang e5520, 8 GB

-robin. weight is proportional to the access ratio, which indicates the performance of the backend server, if the backend server has good performance, you can allocate most of the requests to it. Example: My backend server 172.23.136.148 configuration: e5520 * 2 CPU, 8 GB memory backend server 172.23.136.148 configuration: Xeon (TM) 2.80 GHz * 2, 4G memory I want to send 20 of the 30 requests to the front end to 172.23.136.148 for processing, and the

people think that QPS is the limit of PHP. In addition, there is no authoritative number to respond to the performance of the framework and the impact of the framework on the performance. The purpose of this section is to provide a benchmark reference performance indicator and give you an intuitive understanding of the data. The specific benchmark performance includes the following aspects: 1. Bare PHP performance. Complete basic functions. 2. Performance of the bare framework. Only the simples
