MacBook Air堅持排擠Flash之必要

Flash vs MacBook Air

如果你習慣拿Firefox來做網頁設計,Flashblock大概是一個遲早會裝來用的附加元件(extensions)

Flashblock,顧名思義就是用來擋Flash的工具。

至於,為什麼要擋Flash?

簡單地說,絕大多數網頁上的Flash元件都在虛耗資源。

除了多數Flash元件都是亂槍打鳥的廣告之外,不管你有沒有在看就自行反覆播放的普遍設置,也都平白浪費許多記憶體跟CPU,結果就是拖垮主機效能,還消耗了更多不必要的電量。

Apple MacBook Air剛推出時,由於沒有內建Flash而引發爭議。有人說Apple故意排擠Flash,也許吧。但,排擠Flash有什麼好處?

其實,想想為什麼要在Firefox上裝Flashblock就知道了。

不過,還是有人具體進行了比較科學客觀的實測

Having Flash installed can cut battery runtime considerably—as much as 33 percent in our testing. With a handful of websites loaded in Safari, Flash-based ads kept the CPU running far more than seemed necessary, and the best time I recorded with Flash installed was just 4 hours. After deleting Flash, however, the MacBook Air ran for 6:02—with the exact same set of websites reloaded in Safari, and with static ads replacing the CPU-sucking Flash versions.

根據實測結果,安裝了Flash之後,11" MacBook Air的電池續航力為4小時,而沒有安裝Flash的11" MacBook Air則為6小時。

Flash vs MacBook Air

MacBook Air在硬體規格說它的電池續航力為5至7小時,從實測結果來看,如果不堅持排擠Flash,根本沒辦法吹這種牛皮。
