Independent Testing Methodology & Reproducibility

100% reproducible metrics with zero vendor editorial sponsorship

All hardware benchmarks, TCP socket latency tests, GPU memory bandwidth throughputs, and proxy ban rates documented in this guide were conducted from dedicated bare-metal test clusters in Frankfurt, London, and Ashburn. We purchase all plans under randomized anonymous accounts to ensure zero preferential routing or VIP hypervisor allocation.
