How to fix
Make your Safari faster by modifying DNS settings
on Windows

Hi! My Safari is extremely slow, and it continuously crashes during browsing sessions. My friend told me I could improve its speed by altering DNS settings. Although, I'm a novice computer user. So, could you show me how to make Safari faster?

We have received several reports saying that users encounter slow Safari's browsing speed and they are searching for a way to improve it. Luckily, even inexperienced computer users can make simple changes and enjoy an improved browsing experience. 

If you want to make Safari faster, you should alter Domain Name System (DNS)[ref en-1] parameters. Even though Internet Service Provider (ISP)[ref en-2] DNS servers are not considered the fasters, they are widely used as they function with default computer settings. 

You can improve Safari's speed by changing the parameters to public DNS. In fact, this will affect all browsers installed on the computer, improve the loading time of websites and give more protection than the ISP servers. Public DNS is better because:

1. Helps to decrease loading time;
2. Protects the users from redirects to potentially malicious websites;
3. Delivers accurate results to the user.

Make Safari faster and more secure by altering DNS settings

Unfortunately, if your computer is infected with a potentially unwanted program (PUP)[ref en-3] or malware, altering DNS settings won't help you improve Safari's performance. Usually, ad-supported programs or browser hijackers flood the browser with an excessive amount of intrusive ads and deteriorates its performance.

Likewise, if you think that potentially unwanted programs (PUPs) are installed on your system, you should immediately scan your computer with a professional antivirus or system optimization tool. Our experts recommend using [rev id=”Reimage”] to help you deal with browser hijackers, adware, spyware or even malware.
