For an e-commerce website, it is necessary to use the least bandwidth and server resources to provide faster services for more customers. The satisfaction of users with a web site is mainly measured by access speed.
From the user's perspective, web sites are only divided into "fast" and "slow". Users often do not require large-capacity data transmission, but hope that the website can accommodate more visitors while ensuring performance. The essence of what web users care about is access time. From the perspective of network maintenance, there are many potential factors that cause delays. Generally speaking, the performance of a web site can be improved from five aspects: buffering, compression, CPU optimization, using content delivery networks (CDNs), and client-side software.
