What is the reason for the slow opening of the website?

Slow opening of the website is mainly considered from the aspects of network, hardware, program, system and so on.

First of all, make sure that the server has sufficient bandwidth, and insufficient bandwidth will seriously affect the opening speed of the website. If it is not convenient to increase bandwidth, you can use CDN to reduce the bandwidth consumption of the server.

If the server CPU, IO and memory load is always high, please change the hardware in time, the hard disk is best to use solid state disk, the IO performance is much higher than the mechanical hard drive.

The excellence of the program largely determines the running speed of the website, which requires programmers to have enough optimization experience, which will not be discussed in this article.

If the website traffic is very large, replace the best hardware, the performance is still insufficient, only from the program structure to consider, the use of distributed, unlimited expansion of performance.
