Con­trary ad­vice

Mac Format - - APPLE TALK -

Your sug­ges­tion to change the DNS set­tings (Jan­uary 2015), as a way of fix­ing slow page loads in Sa­fari, in­trigued me. I con­tacted my provider and they said not to do it, as it’s not for the faint-hearted. They thought it could be a cor­rupted DNS set­ting on the iPad and they sug­gested clear­ing the his­tory. I’ve done that, but the jury is still out. David Simp­son Older de­vices, such as the iPhone 4s and the iPad 2, use the A5 pro­ces­sor and only have 512MB of sys­tem RAM. Ev­ery tab con­sumes some of this RAM and it quickly gets to the point where tabs need to be loaded and un­loaded ev­ery time you switch, which makes it feel very slug­gish. Ap­ple is still sell­ing the non-Retina iPad mini, which is A5-based, so even new de­vices aren’t safe.

Switch­ing DNS provider is by no means a com­plete cure, but it can help with web pages that stall part-way through load­ing. And it’s re­ally not as hard as your ISP is mak­ing out. Just Tap Set­tings > Wi-Fi and tap the ‘i’ next to your Wi-Fi con­nec­tion. Re­place the num­bers in the DNS sec­tion with ‘208.67.222.222, 208.67.220.220’, with­out the quotes to use OpenDNS.
