A lot of articles around the web tend to primarily focus on front-end WordPress optimizations and quick ways to speed up your site. Server optimizations such as network latency are sometimes neglected or overlooked. Because of this, we thought it would be interesting to take a deeper look at the importance of network latency and the impact it has on your WordPress site when loading different regions. While a CDN can definitely help decrease network latency, your host server location is still very important, especially if you are serving visitors in a very specific geographical location. Latency matters and we’ll show you a couple reasons why. What is Network Latency? Network latency refers to the time and or delay that is involved in the transmission of data over a network. In other words, how long it takes for a packet of data to go from one point to another. Nowadays this is typically measured in milliseconds, however, it could be seconds depending upon the network. The closer to zero the better. “Latency is the wait time introduced by the signal traveling the geographical distance as well as over the various pieces of communications equipment.” – Whatis.com
