Google and Amazon say warnings about downgrading PC and server performance due to upgrades for processor vulnerabilities are exaggerated


Google and Amazon, two of the world's largest cloud market players and companies using tens of thousands of servers, said the downgrading of PC and server performance due to Spectre and Meltdown vulnerabilities updates is "negligible," " at least in their cases.

It has been hypothesized that the performance of some systems could drop even by 50% after updates attempting to solve these two problems. According to Google, these exaggerated results have arisen because no comprehensive test methods have been used, but only "microbenchmarks" that can provide alarming results

The two vulnerabilities affect almost all existing processors, whether they are for TVs, smartphones, or computers, regardless of the operating system used.

Google, the company that last year discovered the processor design error, has developed special software to cover these vulnerabilities, called KPTI. It is also used by other manufacturers and software developers in their updates.

Amazon, the largest cloud provider in the world and the company that owns the largest online store on the planet, has confirmed what Google said. According to Amazon representatives, the impact of updates will not be severe.

Microsoft, the developer of Windows, the most popular desktop operating system in the world, has not commented on the impact of these updates on system performance
