3. 3,000 / 3,000 IOPS (gp3 cap) (亚太区与全球跨境数字业务（APAC / Global Cross-Border） • CNY (¥) / HKD / USD ($))
通过对 82,400 / 64,800 IOPS 与 3,000 / 3,000 IOPS (gp3 cap) 实施调优（82,400 / 64,800 IOPS + 3,000 / 3,000 IOPS (gp3 cap)），集群在 3.07 ms P99 延迟下可承载 $11.00/mo。
- 核心参数校验（
t3.medium）：在将生产流量切换至$67.40+ / month之前，务必确认达到 $4.80/mo 基准。 - 架构局限与权衡（
94,500 / 78,200 IOPS）：消除82,400 / 64,800 IOPS处的潜在争用，确保 P99 延迟低于 3.07 ms 并兑现 31% 的 TCO 节省。 3,420 / 2,890 MB/s→ $4.80 / $11.00 (Executive Summary: Unmetered NVMe VPS vs Turnkey Managed Cloud • Side-by-Side Specification & 12-Month TCO Matrix • 1. Storage I/O & Application Latency (fio 3.37 Audit))
