日本節點到美國之間的連線
使用日本的機器直連 cloudflare NRT 日本節點 ，以 jquery 1.8.2 為 93k，由於使用 ab 指令來測試。
測試由 NRT 到 US 的速度
在 cloudflare page rule 設定 cache level = bypass 來避免快取。

台灣節點到美國之間的連線
再來是台北節點的測試，使用 hinet ipv6 來直連台北節點
Non ARGO: TW test point → cloudflare TPE (cache bypass) → US Server

結論
日本節點實測連線時間 -70%，台北節點實測連線時間 -64% 。
但是否採用 argo ，要視你網站系統的架構而定。以本站說，台灣訪客的走法有這兩種各佔一半：
- 台灣訪客 → 台北節點 → 美國主機
- 台灣訪客 → 日本節點 → 美國主機
以上述的測試來說都可以讓 TTFB 少一半以上，這對 SEO 和廣告效益會有幫助。
但是否採用 argo 還有另外一個要考量的就是口袋深度，無論是否有快取 要價 0.1USD/GB ，本站也要再考量看看。
