The more heavily your Mac has to depend on virtual memory, the slower it will perform. Physical memory accesses installed RAM chips. Physical memory is faster. Virtual memory uses space on the Mac’s drive. Macs depend on a combination of physical memory and virtual memory to get things done. You might also try using Google’s Chrome: If one tab misbehaves in Chrome, you can use Activity Monitor to zap it without bringing down the whole app. To reduce the odds that a Safari slowdown will recur, minimize the number of webpages you keep open at one time. If webpages are loading extremely slowly, and if the % CPU for Safari and/or Safari Web Content remains high, it’s time to take action.
To find out, select the app and click the Quit Process button.īy far, the most likely source of trouble is Apple’s Safari (and more specifically, a webpage that uses Flash).

It may, for instance, have an unusually weak Wi-Fi connection. If the slowdown occurs on only one machine, the problem most likely originates with that Mac. Test all your Macs: If you have more than one Mac, test the Internet speed on all of them. Alternatively, your ISP may offer to check and perhaps fix your modem connection via remote commands. If so, you’ll have to wait for someone else to correct the issue. If you detect a slowdown, call your ISP to ask if it is experiencing general problems that may be affecting you.

You probably pay for certain upload and download speeds-look at your bill or check with your ISP to see what those speeds are supposed to be. Since I use Comcast Internet service, I go to Comcast Speed Test. IDGĬheck your speed: If you can get the page to load, go to a site that tests Internet connection speeds. Are you even connected to the Internet? Here, Network Diagnostics reports good news.
