Refreshing php websites seems a little slow

It seems a little slow to refresh and browse php websites. What are the factors that affect the load time of Website?

Mysql database

Considerations: Design of database query statements? Have you set the cache? Php statement usage?

1. network problems
2. data IO

Generally, I/O processing is the slowest. add some timestamps to your program to check the execution time of each command.

In addition to the compilation cache and data cache mechanisms, the impact on the database is relatively large without considering some objective factors such as hardware.

It is best to analyze the SQL desc you executed, which may also be caused by the network,

In addition to some objective factors such as hardware, the impact of the database on compilation cache and data cache is relatively large, and the effect of adding a Cache mechanism is obvious, when the website browses a large amount of data, some cache is created. Otherwise, the pressure on the server will increase each access.

Other factors will accelerate the speed of opening and loading some websites if you are considerate?

The company website introduces a Sina Weibo interface, and then checks the website load in the background. This Sina Weibo interface needs to be loaded for a period of time.

So load it asynchronously. Weibo information displayed on many websites is asynchronous.

Or you can cache this.
