Google Technique Offers Spectre Vulnerability Fix with No Performance Loss
The solution, called Retpoline, was created by Google software engineer Paul Turner to mitigate the Spectre vulnerability without a loss to performance.
The thing Intel is trying to sweep under the rug but that's killing Microsoft and AWS… yeah Google fixed it and then offered to for free to everybody else.
“We believe that Retpoline-based protection is the best-performing solution for Variant 2 on current hardware. Retpoline fully protects against Variant 2 without impacting customer performance on all of our platforms. In sharing our research publicly, we hope that this can be universally deployed to improve the cloud experience industry-wide.”
