AffixIO Multi-Terminal Parallel Operations

Version 1.0 · Published April 2026 · Technical Whitepaper

This whitepaper evaluates parallel workload behavior when multiple merchant terminals reconnect and sync simultaneously, with isolated terminal identities per worker.

Benchmark highlights

• 8 concurrent terminals, 10 transactions each.
• 80 planned transactions, 80 successful.
• Wall clock for total workload: 1145.9 ms.
• End-to-end p50: 74.67 ms, p95: 120.99 ms, max: 143.40 ms.

What teams can use this for

• Capacity planning before high-density merchant events.
• SLO design using contention-aware percentiles.
• Operational validation of read-after-write visibility behavior.
• Proof that parallel sync remains under practical merchant latency targets.
