1. Select a good host
Try not to use a free host or a shared host (GoDaddy, bluehost, etc. so-called unlimited bandwidth, unlimited sites and other hosts)First of all, your domain name and your host is best in an IDC where, if not, it is recommended that you use a good reputation of the DNS service providers, so that the d
Resource utilizationRefers to the use of different system resources, such as server CPU utilization, disk utilization, and so on. Resource utilization is the main basis for analyzing system performance Index and improving performance, so it is the focus of Web performance testing work.Resource utilization is mainly for Web server, operating system, database serve
Experience in performance optimization and Performance Optimization
Communicate with colleagues. After a year or two of the previous online system, there were 20 millions or 30 millions million data records.
System, there is no way to deal with so much data
There are two reasons: one is that the data volume is not considered during design.
Another problem is that the data volume is not noticed when writ

Chapter I: Loading and executingThe browser's JavaScript engine is the compiler layer optimization;
When a browser executes JavaScript code, it cannot do anything else at the same time (a single process), meaning that every time the Mainstream browsers are allowed to download JS in parallel.
Reduce the number of external chain scripts will improve performance (merge JS)
