Wow, alignment still matters, and it matters a lot (24 -> 33 ops/us)! Thank you @kaivalnp for testing. Was this an `aarch64` CPU (Graviton 3 or 4?). It's frustrating how the CPU just silently runs slower ... but what else could it do. I wonder whether modern x86-64 (Intel, AMD) CPUs also show this effect. I'll test this PR on nightly Lucene benchy box ([`beast3`](https://blog.mikemccandless.com/2021/01/apache-lucene-performance-on-128-core.html)). -- This is an automated message from the Apache Git Service.
