Safari Tabs/clear cache

Have a look at Activity Monitor’s RAM tab and you’ll see that some of the most memoryintensive processes are Safari tabs. The more you have open, the bigger the performance hit. Close the ones you’re not using – bookmark them if you think you’ll need them again. Next, open Preferences from the Safari menu and, in pre-Yosemite versions of OS X, click Reset Safari in the Safari menu and choose Remove all Website Data > Reset. In Yosemite, choose ‘Clear History and Website Data’ from the Safari menu and pick an option from the

drop-down menu.
