There are two effective methods to improve the load time — data caching and using a content delivery network (CDN). Our article aims to compare them in terms of speed of data load. When we talk about the speed of a website, most often we mean the speed of its content loading.

Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. This avoids thrashing caches too much for B and evens out the pressure on the L3 caches of the machine.
