5 Tips to Reduce Latency in Internet Connection (Quick Tips)

This is the whole point of my article. Latency does cause issues unrelated to bandwidth or congestion. Those issues can be reduced with planning. I will now explain why fragglet is wrong and Bill is right.

That's because even though his examples are a bit dated how many people are still using a The key to this issue is a simple formula for Web page download time. It explains Web page response time using "The Complete Formula" shown here. Alberto's contribution was in simplifying this formula to the version shown in his article's Figure 1, reproduced below.

This formula makes several generalizations and assumptions, and its accuracy varies through the possible range of values it tends to overestimate below eight seconds and underestimate over eight seconds. Actually, even that explanation hides some further assumptions. His reference to eight seconds involves assumptions about typical connection latency and bandwidth, typical Web page sizes, and the typical number elements separately downloadable files that make up a Web page.

But, as he says, for the purposes of this article, however, it will do just fine, since it introduces the key variables that impact page response time and shows you how they relate to each other, without introducing excessive complexity.

Alberto describes the six key variables as follows:. There is no question that these six variables do account for Web page response times, and do operate in the directions prescribed in the formula. As one confirmation, consider the authoritative textbook on the quantitative aspects of computing, Computer Architecture by John L. Hennessy and David A. In the 3rd Edition , Chapter 8 covers networks, and page gives this simple formula for the total latency of a message:.

The Web uses TCP, which transmits data as message segments comprising one or more packets, with each segment being acknowledged. This demonstrates that the formula is correct, but if we wanted to use it to predict page download time, the task of selecting the right values to plug into those variables involves some complications.

Alberto does explain how to use the formula. But in practice, I would expect those directions to produce a worst-case estimate for response time, mainly because the value of the Turns variable should probably be lower than Alberto's method suggests.

Three factors affect the estimation of turn counts:. Fortunately, such complications do not prevent us from using the formula to explain the relative importance of bandwidth and latency. To demonstrate this, consider a newer version of the formula shown in Figure 2 below. The only difference between this and Alberto's version is in its use of curly equals, signifying "is approximately equal to":.

The NetForecast paper goes on to discuss how each of the six factors affects response times, using Figure 3 below to summarize its points. In the analysis above, I showed that as connection bandwidth increases, the effect of the first factor in the response time formula approaches zero. No such scaling effect exists for the second factor -- neither latency nor turns can ever be made to approach zero.

In fact, as Web sites and applications keep growing in sophistication, turns are increasing. Even the newest AJAX technology may increase, not reduce, turns, as designers attempt to replace large monolithic file downloads with multiple smaller requests. Unless those smaller requests can also be designed to happen asynchronously, while the user is doing something else, they will only add to the delay due to network latency.

And until someone finds a way to move bits faster than the speed of light, that's not going to change. View Printer Friendly Version. Email Article to Friend. There are a number of factors that can impact the speed of data transmission. Overcrowded bandwidth is a factor. Errors and the resulting retransmissions are a factor. The speed of switching and routing equipment is a factor. The speed of every component in a client-server system is a factor. I have nothing so complete or eloquent as this to describe the "latency factor", but I do have an experiment that I do with people when they don't get it.

I have them sit at a "representative client computer". I then have them request a pre-configured "empty" html page with one embedded link to a 1kb file more often than not "spacer. Next I have them launch an object from the site of interest that I have previously downloaded to the desktop. The object is often a large. I also make sure that the relevant "speed launch" services are turned off, since we obviously can't control whether or not a client will have these running.

We capture the "click to display" time for that as well and add it to the first number. Next after shutting down the speed launch services and whatever else to ensure I'll be comparing at least one type of apples to another type of apples I have the person navigate to and launch the same object through the site of interest and time that. Finally, I subtract the "spacer.

The answer, I tell them, is the parts that they have some control over unless they can make the. The rest is latency. That they can't control unless they can:. Executive Director, Association for Software Testing www.

This is an outstanding analysis of the issue, and I am humbled by your review and support. I'm sorry it took me so long to find your page.

Keep up the great work. Apparently there was not enough latency for me to correct my comment, before it reached your server! Thanks for the follow-up, although I only just found it!

You should really drop people an email when you post something like this. In the examples that you describe relating to websites , your reasoning is to be correct. Downloading a website requires downloading several pieces of media HTML, images, etc that form the page.

In this scenario, latency does have an effect. However, this scenario is a very specific one. If you are downloading a 50MB file from a website, for example, latency is not likely to have much effect.

You have an initial latency in making the request, but after that your download speed is solely dependent on your bandwidth. This is the main reason that I posted my responses in the first place. In his discussion of latency, Bill specifically said "As the latency increases, the TCP window shrinks, meaning the sender sends less data before waiting for an ACK", which is patently false. He asserts that latency affects download speed as in the 50MB file example I previously gave , and this is not the case.

Furthermore, while latency is an issue, the main cause of latency is queueing due to saturated network links - a problem caused by lack of bandwidth. When there is no available bandwidth, packets are queued and latency increases.

As a classic example, try playing a computer game like CounterStrike while downloading a large file over the same connection. Your ping time shoots through the roof, because the game packets are queued, waiting for the download packets to be transmitted. Updating the firmware often increases the bandwidth speed and reduces latency. My router had issues of with reconnecting loops, which the firmware update has totally fixed. My pings in some game servers improved dramatically as well.

I know this tip is too simple. But believe me, this works the best in my opinion. I recently bought a laptop for writing on TechiePaw. However, I can also play some online games like Dota 2 and CS: GO on my laptop. Try this before replacing your router.

But this is worth trying. This also improves your loading speed as well as download times. This will dramatically improve your internet speed and thus reducing your latency and ping in online games.

For several years, I managed myself with a 1 Mbps connection which is god-damn slow! So, if none of my personal tricks worked for you. I currently use a 5 Mbps connection which is not bad. However, the above four tips are what I use to stabilize and boost my internet speed. Investing in a better router from Netgear or other reputed brands will definitely kill some money, but they are great for the long run.

I no longer get lag spikes and high pings in online games, just by tweaking a few things. So here are the solutions that I have tried and got good results.

Four out of five tips are totally free and actionable. You can just experiment and implement each of them to try to reduce latency of your internet connection.
