All You Need to Know about Latency in Web Hosting

Latency is known as the delay that your users experience. For this reason, it is one of the factors that every website owner in Tennessee should consider. According to professional website hosting company in Memphis, Tennessee, latency is majorly affected by the quality of networking as well as the geographical distance between your target users and server. Furthermore, server configuration and hosting infrastructure also play a critical role in cutting down latency.

Understanding Latency
Regardless of where your server and target audience are located, there will always be a delay. This is because the data and information is transferred through different switches that are located between networks and along the fiber optic routes around the world.

Latency and bandwidth are two different things. Even though bandwidth has something to do with speed, a connection with high bandwidth/high latency will reach its maximum data transfer rate but with a major delay because of high latency. To illustrate this case, try watching a live telecast where the interviewee and interviewer are located in both ends of the world. You will definitely notice that there is a delay before the interviewee receives the question of the interviewer.

In the web hosting context, latency is only about 10 to 500 milliseconds when loading web pages. Nevertheless, delay still varies from users depending on how fast their internet connection is.

Analyzing Latency
In order to fully assess and examine the latency, you must first understand the existing latency in your infrastructure and applications. In addition, analyzing latency also necessitates determining the levels of latency you can have, as well as every hosting decision you have made.

Cutting Down Latency
The fastest way to cut down latency is to tweak your web elements and content. Even though it is quite difficult to pinpoint which elements slow down your key web pages, keep in mind that Google has conducted a study where they’ve proven that there was a 25% decrease in the use of their search engine because of the 0.4 second delay in displaying page one to page two of the results. This means that website elements really play a huge role when it comes to delay and level of user experience.

Aside from fine-tuning your web elements, it is also advisable to make necessary adjustments in your location, server and content delivery network (CDN). Here are some of the proverbial best practices to help you get started:

  • Add cache-control header
  • Organize ETags
  • Utilize GET for Ajax request
  • Flush buffer early
  • Avoid Empty Image src
