Internet speed is a critical measurement Start Testing Your Internet Speed Right From the Desktop Start Testing Your Internet Speed Right From the Desktop We all know about Speedtest's online interface, but now you can test your internet even more conveniently. Read More in the 21st century. All the information in the entire world is within the reach of our fingertips — if only it would arrive on screen a little faster. Slow internet speed is annoying. In fact, it is downright infuriating. So, it stands to reason there are thousands of tips detailing exactly how to boost your internet speeds into the stratosphere.

Unfortunately, they don’t all work. A number of tips stem from technical misunderstandings, while others are just straight-up myths. I’m going to debunk some of those myths for you, right now.

Myth 1: Clearing the Cache = Instant Speed-Up

This is a commonly cited internet speed boost, but it isn’t true. However, I can understand the misinformation surrounding this myth. Clearing various caches 7 Hidden Windows Caches & How to Clear Them 7 Hidden Windows Caches & How to Clear Them Cached files can take up a lot of bytes. While dedicated tools can help you free up disk space, they might not clear it all. We show you how to manually release storage space. Read More — think temporary internet files, cookies, website data, browsing history, and so on — can indeed be useful, but it won’t have a positive effect on internet speed.

In fact, it will do the opposite.

Cookies, website data, and other caches are used to store commonly accessed data. In turn, this actually speeds up your internet browsing experience as less resources are required to load frequently-visited pages.

Exceptions

Clearing your cache isn’t a bad piece of advice. It just won’t speed up your internet connection. However, there are occasions where it is the right thing to do. For instance, the cache for a specific application can become corrupted, or just out of date. At this time, clearing the cache would be sensible.

Myth 2: Disabling IPv6 Provides a Boost

This is another internet speed boost myth that — like all good legends — is borne of a misinterpretation. All major operating systems have built-in support for IPv6 10 Networking Terms You Probably Never Knew, And What They Mean 10 Networking Terms You Probably Never Knew, And What They Mean Here we'll explore 10 common networking terms, what they mean and where you are likely to encounter them.

Furthermore, the internet has completely exhausted its reserves of older IPv4 addresses IPv4 Addresses Have Run Out: Here's How It Affects You IPv4 Addresses Have Run Out: Here's How It Affects You We're out of IPv4 addresses yet we aren't adopting IPv6. What's the problem? How can we speed everything along? But most importantly, why does it even matter? Read More (bar the African continent, but they’re beginning to run low, too). This means new websites and services will be hosted on IPv6 addresses. Subsequently, turning off IPv6 support will literally cause some sites to fail to display.

This myth propagated in the early days of IPv6. In 2010, when Mozilla Firefox 3 was released, it attempted to resolve DNS addresses with IPv6, before switching to IPv4. The failure to find the IPv6 address and subsequent switch to IPv4 took time. People complained, and Mozilla fixed the bug.

Configuration

Is there more to the myth? It is true misconfigured IPv6 settings would slow your connection to certain websites down, but not all of them. At worst, your browser would fall back to IPv4 DNS, and the site would load. IPv6 is the future (and at this point, the now) of the internet. Your ISP understands, and will be prepared.

Myth 3: SSL Is Network Intensive

The Secure Sockets Layer (SSL), and its successor, Transport Layer Security (TLS), are cryptographic protocols. SSL/TLS provide communication security How Web Browsing Is Becoming Even More Secure How Web Browsing Is Becoming Even More Secure We have SSL certificates to thank for our security and privacy. But recent breaches and flaws may have dented your trust in the cryptographic protocol. Fortunately, SSL is adapting, being upgraded - here's how. Read More throughout the internet. The protocols are present in a massive number of common internet applications, including web browsers, email, instant messaging services, and VoIP (voice-over-IP) services, such as Skype. It does have a slight network overhead, but versus the security advantages it brings, it is utterly negligible.

In fact, there are two technologies in play designed to keep the encryption and communication process running as smoothly as possible. These are known as False Start and Session Resumption, as MaxCDN explains:

False Start speeds up the initial connection process by giving the sender a head start on the receiver. A normal TCP connection (known as a TCP handshake) forces one party to wait for a response from the other before continuing. With false start, the sender starts sending data when the handshake is only partially complete. By the time the handshake is finished, data has already been transferred…

Session Resumption caches keys and connection information on both the client and the server. When a client connects to a familiar server, both parties check and compare their caches for matching session IDs and parameters. Matching sessions result in a shorter handshake, while new connections result in a newly created session ID. While this reduces the number of round trips, it requires the server to maintain a list of thousands or possibly millions of unique session IDs.

Myth 4: Internet Speed Boost Software

In the heyday of dial-up modems Types Of Internet Access Technologies Explained, And What You Should Expect Types Of Internet Access Technologies Explained, And What You Should Expect What kind of Internet access do you really have? Broadband? High Speed? Wireless? Satellite? Fibre? Read More , internet speed boosting software was insanely popular. These carried names such as SpeedConnect Internet Accelerator and Internet Cyclone. They claimed to automatically optimize Windows and network settings, providing an instant and miraculous boost to internet speed.

Speed boosting utilities were snake oil then, and so they remain. Your broadband/fiber connection will not be boosted by third-party software. At best, the software will do nothing. At worst, it will install spyware and/or malware, significantly slowing your connection — and causing a significant amount of alternative issues, too.

Myth 5: The DNS Flush

Our final myth concerns the domain name system (DNS). A commonly cited internet speed boost is to run the following command:

ipconfig /flushdns

This command immediately flushes the DNS cache. However, this has a negligible effect on internet speed. In fact, much like the clearing of cookies and other caches as mentioned in the first myth, flushing the DNS can actually temporarily slow your speed as the DNS cache repopulates.
