If you are experiencing issues with page loading speed issues with Overture, particularly if others in your team are not experiencing the same issues then the most likely problem is with your DNS Cache. You will need to clear it to fix the issue.
How to Clear DNS Cache on macOS
In order to clear the DNS cache on a Mac, you’ll need to open the native command-line interface known as Terminal and run the appropriate command. This process varies based on which version of macOS you’re running.
Ventura & Monterey
If you’re working on macOS version 10.11 or above, open the command line interface by clicking on Go > Utilities:
Then select Terminal. Once it opens, run the following command:
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
You’ll be prompted to enter your computer password: After you’ve done so, your DNS cache should be clear.
Lion, Mountain Lion, Mavericks, El Capitan, Sierra, High Sierra, Mojave
If you’re working on macOS version 10.11 or above, open the command line interface by clicking on Go > Utilities:
Then select Terminal. Once it opens, run the following command:
sudo killall -HUP mDNSResponder
You’ll be prompted to enter your computer password: After you’ve done so, your DNS cache should be clear.
Yosemite
You can access Terminal by the same method described above for any macOS version. In Yosemite (10.10), once the window opens you’ll need to run the following command:
sudo discoveryutil udnsflushcaches
Enter your computer’s password and the DNS cache should successfully flush.
How to Clear DNS Cache on Windows
Flushing your DNS cache on a Windows computer is fairly simple. Here’s how to accomplish this task on Windows 10, 8, 7, and XP.
Windows 10
To clear your DNS cache on a Windows OS, you’ll need to open Command Prompt, the system’s command line interface. You can access this program in Windows 10 by clicking on the Start button. Then navigate to Windows Systems > Command Prompt:
ipconfig /flushdns
This command should return a confirmation that the DNS cache has been successfully flushed:
Windows 8
Clearing your DNS cache in older versions of Windows requires the same command ipconfig /flushdns. However, the steps for accessing Command Prompt are slightly different between versions.
In Windows 8, open the Apps screen. On the far right side, find Windows Systems and select Command Prompt.
Once the program opens, run ipconfig /flushdns. You should receive a confirmation once the DNS cache has been cleared successfully.
How to Clear DNS Cache on Google Chrome
Finally, as we mentioned at the beginning of this post, you may have cause to clear your browser’s DNS cache rather than your OS’s. In Google Chrome, you can do so by entering the following into the address bar:
chrome://net-internals/#dns
Then click on the Clear host cache button
