5 Ways to Improve Internet Speed on a Windows Computer

Finding the fastest server

Before a browser can establish an Internet connection, it must resolve the DNS name of a local web server to your computer’s specific IP address. DNS servers are the essential intermediaries that link your system to virtually all of the resources scattered across the web. It’s important to make sure the DNS server selected is the fastest possible one available in your area—a task your Internet service provider does not bother to do.

And since many DNS servers are in the public domain, software that finds the fastest one available for a given ISP with a specific connection in a particular location at a certain time of day is an elegant solution to an easily identified but fairly complex problem.

NetBooster uses this precise strategy to help optimize your Internet connection—in this case, with an overlooked available resource right outside your home. By searching for the fastest possible DNS server in your area and letting you simply click to connect to it, NetBooster can deliver increased network speed, so you can enjoy less buffering delays and greater bit resolution in online streaming and TCP-bound gaming.

Improving Windows settings
In addition to outward-reaching solutions to Internet speed optimization, breakthrough iolo Labs research has unearthed a whole cache of underperforming Windows Internet settings within your computer, and they too are crying out for optimization.

Regardless of how new your OS may be, when these hidden settings are adjusted correctly, the difference in your Internet experience can be significant. Recent benchmark tests comparing NetBooster’s adjustments to the default settings show boosts in download speed by an average of 23%, and by as much as 37%.* Let’s look in detail at what two of the most critical of these settings can do.

Adjusting data packet size

Data is transmitted across the Internet in packets. One way to increase the efficiency of this process is to discover the largest possible size (in bytes) a data packet can be for a given network before it has to be broken up to transmit. This value, often determined by your router, is called the Maximum Transmission Unit (MTU). NetBooster automatically discovers this value, takes the MTU setting in Windows out of “autotune” mode, and fine tunes it, helping to eliminate data fragmentation at routers and so reducing network congestion.

Rethinking Nagle’s algorithm to reduce latency
An engineer named John Nagle invented a way of increasing TCP/IP network efficiency by reducing the overall number of packets that need to be sent over a network. It works by coupling very small data packets together, but often at the expense of real-time responsiveness because the algorithm delays in sending small outgoing messages until they collectively reach the desired amount of bytes to make them “worth” sending. Some networked multiplayer video games can suffer from Nagle’s algorithm because these programs assume gaming actions are sent immediately, not in delayed coupled packets. Therefore, disabling the algorithm can help eliminate the stuttering time delays in gaming known as latency.

The impact of disabling Nagle’s algorithm (or De-Nagling) was examined by iolo Labs with World of Warcraft as the test scenario. Both in-game latency reports and a Wireshark packet analyzer were used, and the end results showed on average a 20% reduction in game delay.**

De-Nagling improves TCP-bound, networked games like World of Warcraft, Guild Wars 2, Eve Online, and Flash-based games such as League of Legends. NetBooster lets you control when and if you decide to De-Nagle, as disabling Nagle’s algorithm may negatively impact large file transfers in a very high latency network.

Optimize automatically or manually
No less than 14 total settings within Windows TCP Global Parameters can and should be adjusted from their default settings to best handle network traffic on your particular system. NetBooster automatically sets each of these to their optimal values.

Alternately, by choosing “Customize Advanced Internet Settings”you can manually adjust each value yourself. Within this interface, the “Restore All to Orig” button allows you to easily revert to NetBooster’s original configuration if after tweaking the settings you experience problems with the network. In future articles and tips, we’ll walk through several of the features advanced users can access in NetBooster’s manual mode to finely adjust Internet settings to meet their specific network needs.

Instead of putting up with the bitter indignity of an underperforming Internet stream, System Mechanic users can deploy NetBooster to help gain significant, welcome increases in Internet speeds, resulting in improved bit rate and picture quality of TCP-bound videos and games, less time in the dreaded “Buffer Zone,” faster downloads, snappier page loads, and an increased rate of large file transfer.

To run NetBooster in automatic mode:

Let ActiveCare^® handle it

System Mechanic automates a series of maintenance actions while your PC is idle. This process is called ActiveCare and it not only ferrets out clutter and obsolete files and programs, but it will automatically optimize your Internet settings if NetBooster is enabled. To be sure that it is:
