[v2] Performance comparison between ARM64 and x86_64 for InfluxDB

I'm evaluating InfluxDB deployment on ARM64 (e.g., AWS Graviton) vs. x86_64. My pure CPU test with bc shows ARM is about 15% slower (22s vs 19s). I'm wondering how InfluxDB performs on ARM under high-concurrency query workloads, given the weaker memory model.

Are there any official benchmarks or community data comparing InfluxDB on equivalent ARM and x86 hardware? Also, any recommended configuration adjustments for ARM deployments? Thanks.

Start with the InfluxDB deployment context described in the issue and compare equivalent ARM64 and x86_64 hardware, including AWS Graviton, under high-concurrency query workloads. Done means providing reliable benchmark data and documenting any configuration differences relevant to ARM deployments.
