10 Ways to Improve Your Site Speed

Latency
Latency is the amount of time it takes for the host server to receive and process a request for a page resource. The amount of latency depends largely on how far away the user is from the server, but it's typically 75-140 milliseconds per resource for desktop users. When you consider that a typical web page contains around 100 resources, you can see how these milliseconds can pile up.
