We all know very well that the Specter and Meltdown vulnerabilities have brought problems to various devices. Although most manufacturers report that performance loss after patch upgrades are minor, the truth is that this is not so. In a test run with an iPhone 6, the performance loss is around 40%, yes, it is true and we have to believe that it is drastic fall.
iPhone 6 Shows Huge Drop In Performance
The Specter and Meltdown vulnerabilities have brought problems to various devices. Although most manufacturers report that performance loss after patch upgrades are minor, the truth is that this is not so. In a test run with an iPhone 6, the performance loss is around 40%, yes, it is true and we have to believe that it is drastic fall.
If you have an iPhone 6 it’s best to think twice about upgrading to iOS 11.2.2. According to a test conducted by the site managers melv1n.com, in the case of an iPhone 6, the performance loss is around 40% and as we told earlier that it is drastic fall.
The Specter and Meltdown Vulnerabilities
Both vulnerabilities allow hackers to access sensitive information by accessing the device’s base memory. The first vulnerability, Meltdown, successfully removes the barrier between user applications and sensitive parts of the operating system. The second vulnerability – Specter – also found on AMD and ARM chips, that could make more vulnerable applications publish the contents of their memory.
Applications installed on devices work normally in ‘user mode’. If an application needs access to a protected area – access to the disk, network, or underlying processes – it must request permission to use the “safe mode”.
In the case of Meltdown, a hacker can access security mode and main memory without asking permission, successfully removing this barrier. This allows the eventual theft of RAM information from current applications such as password managers, search engines, emails, photos and documents.
The Tech Giant Apple’s Fix Dramatically Lowers iPhone 6 Performance
According to the tests, which report that they used a good battery, the loss of single core performance of iOS 11.2.2 compared to iOS 11.2.1 is around 41%. In the case of the test performed at the multi-core level, the performance difference is 39% and yes this amount of fall is also drastic.
According to data from the site melv1n.com, in addition to the loss of performance of the CPU, the speed of access to memory is also affected. The results of all tests can be found here.
So, what do you think about this performance terminating patch of the tech giant Apple which has drastically affected the performance of the tech giant Apple’s iPhone 6? Simply share all your views and thoughts in the comment section below.
