[question] 怎么优化第一次访问的333ms
[try to solve] The ~333ms is SEA PoP Cache miss: Worker R2 get + gunzip + response assembly, not slow transfer. Prefer: (1) post-deploy warmup (curl sitemap/hot URLs or a script writing Cache) so real users hit miss less; (2) store plaintext in R2 and skip gunzip (measure whether larger objects cancel the win); (3) keep the bucket region near main traffic; (4) put popular tools on Assets like homes; (5) Tiered Cache / Cache Reserve to reduce cross-PoP cold. Do not remove the Worker just to save ~300ms. Streaming gunzip helps little. Warmup has the best ROI first.
