Most web browsers use a feature called "caching" to display frequently used information, images, and web resources. Caching stores or "caches" this information on your computer, so your computer doesn't have to download the same information every time it visits the same webpage. Caching makes subsequent visits to the same website or webpage faster.
To clear Safari's cache on a Mac (Safari 6.0 and later)
- Close any open Safari windows.
- Choose Safari > Preferences > Advanced.
- Select the checkbox labeled "Show Develop menu in menu bar".
- Close the Advanced window.
- From the Safari menu bar, choose Develop > Empty Caches.
Safari 5.0.1 or later: Slow or partial webpage loading, or webpage cannot be found - Apple Support
http://support.apple.com/en-us/HT203387
When loading webpages in Safari 5.0.1 or later, you might experience the following:
- Slow performance
- Partially-loaded pages
- Webpage "cannot be found" message
Your DNS server(s) or your router might be affected by DNS prefetching in Safari 5.0.1 or later.
Try a different DNS service, such as one of the DNS services below. This will test to see if the root cause of your issue lies with your selected DNS servers.
For information about how to change DNS settings in Mac OS X, see Editing DNS and search domain settings.
If the issue persists in Safari, return to your original DNS server settings if desired, then continue with the next section.
Choose your operating system below to learn how to disable DNS prefetching.
- Open Terminal (in /Applications/Utilities).
- Execute the Terminal command below to disable DNS prefetching:
defaults write com.apple.safari WebKitDNSPrefetchingEnabled -boolean false
- Quit Safari, then open it again and test for the issue.
I hope this information helps ....
