IOS – Are there performance issues with iOS 6 running on iPhone 3GS

iosiphoneperformance

My brother has an iPhone 3GS. The upgrade to iOS 5 has considerably slowed down the device. Will the upgrade to iOS 6 slow down the device even more?

Will iOS 6 work well (not any different from iOS 5) on an iPhone 3GS?

According to this ArsTechnica article

iOS 6 doesn't make the iPhone 3GS any slower or more difficult to use than it was before, which should be good news to anyone who keeps theirs around as a secondary or backup phone—indeed, it's pleasantly surprising how many of the refinements and improvements make their way down to Apple's oldest-supported piece of iOS hardware. However, that hardware has been surpassed so thoroughly by other iOS and Android handsets at this point that it's difficult to recommend it as a primary handset. You don't have much to lose if you upgrade a 3GS to iOS 6, but there's a lot more to gain by investing in a newer device.
