# bench-cdn.sh — UIkit CDN 测速脚本（国内 / 海外双视角）
|
|
#
|
|
# 用途：对比"自建 R2 自托管 uikit"与"公共 CDN (cdnjs.snrat.com)"的加载速度，
|
|
# 用于验证/复测 2026-09-05 的 CDN 迁移是否持续生效。
|
|
#
|
|
# 用法：
|
|
# bash dev/bench-cdn.sh cn # 国内本机：每资源 5 次全量下载取中位
|
|
# bash dev/bench-cdn.sh global # 海外：check-host.net 多区域节点 (p50/p90)
|
|
#
|
|
# 数据结论参考（2026-09-05 基线，国内中位）：
|
|
# css R2 0.864s -> snrat 0.200s (4.3x)
|
|
# js R2 0.796s -> snrat 0.163s (4.9x)
|
|
# icons R2 0.824s -> snrat 0.177s (4.7x)
|
|
# 海外（check-host p50）：css 打平；js R2 372ms vs snrat 647ms (R2 略快)
|
|
# 结论：站点访客以国内为主 -> snrat 净收益大；海外属轻微下降可接受。
