Yesterday AWS announced the public preview of Amazon Linux 2027 as their successor to the current Amazon Linux 2023 in-house distribution. With all the software upgrades and improvements like building packages now with link-time optimizations (LTO), enforcing x86-64-v3 builds, and other changes, I was eager to run some performance benchmarks of Amazon Linux 2023 vs. Amazon Linux 2027 in the EC2 cloud.
