Vault Benchmarks Reveal Memory as Scaling Bottleneck
HashiCorp Vault benchmarks show reads are 2.3x faster than writes, and payload size significantly impacts performance. Memory, not CPU, becomes the primary constraint at 500 concurrent users. For SSH, ED25519 doubles concurrency headroom over RSA-2048.

The findings offer concrete operational guidance for scaling Vault, but real-world deployments may face additional constraints beyond these controlled benchmarks.
