避免出現瓶頸要求
總覽
這項稽核會找出阻礙第一個廣告請求的長時間執行要求。這些要求是在第一個廣告請求提出前所發出,且在發出第一個廣告請求前收到回應。減少這些封鎖請求的數量和持續時間,就能縮短第一個廣告請求的延遲時間,進而加快廣告載入速度。
建議
這項稽核的詳細資料包含前 5 大造成阻斷的要求 (依費用)。目標是移除或縮短這些要求的持續時間,以加快廣告載入速度。以下提供幾個訣竅:
- 排除不必要的要求。
- 先延遲非關鍵要求,直到廣告載入完畢後再進行。
- 同時 (而非依序) 發出要求。
- 透過 HTTP/2 等最佳化後端服務,藉此改善回應時間
這項稽核會依據費用顯示前 5 大瓶頸要求。要求的成本計算方式如下:
request duration + (request self-time * 3)
其中, request self-time 等於要求時間長度減去其他要求的封鎖時間。只有自身時間超過 250 毫秒或時間大於 1 的要求,才會納入計算。

Actions to reduce delays include eliminating or deferring non-critical requests, issuing requests in parallel, and improving response times. The cost of a request is its duration plus three times its self-time (duration minus blocked time). Only requests with self-time above 250ms or duration above 1s are considered.\n"]]
