Its essence is to optimize through various technical means.

There are two parts:

1. Front-end performance

Its essence is to optimize the front-end page presentation time that users actually feel through a variety of technical means.

The method of front-end performance optimization is relatively standard. Tools such as PageSpeed, Yslow and so on can systematically analyze the front-end performance problems and give corresponding solutions.

two。 Back-end performance

01: caching is the most important technical means used in the high-performance architecture of back-end servers in the industry.

02: clustering can also improve the processing performance of the backend from the perspective of computing power.

Cache:

The idea of caching is used whenever you want to improve performance.

If the data in the cache is obtained by complex calculation, then when the cached data is used again, it can be used directly without having to repeat the calculation. In this sense, caching also has the ability to reduce
