Performance Lab

外掛說明

Performance Lab 是致力於加強網站效能功能的集合,大部分的功能最後會整合至 WordPress 核心程式中。這個外掛能讓網站管理員在這些功能整合至核心程式前,啟用並測試個別功能以了解相關功能,並提供意見反應讓開發人員改進相關解決方案。

安裝方式

自動安裝

  1. 前往 [外掛]→[安裝外掛]
  2. 搜尋「Performance Lab」
  3. 安裝並啟用 Performance Lab 外掛。

手動安裝

  1. 將外掛安裝套件解壓縮所得的 performance-lab 資料夾上傳至網站的 /wp-content/plugins/ 目錄。
  2. 前往 [外掛] 頁面。
  3. 啟用 Performance Lab 外掛。

外掛啟用後

  2. 啟用想要使用的個別功能。

常見問題集

開發這個外掛的目的為何?

Performance Lab 的主要目的在於這些效能功能整合至 WordPress 核心程式前,讓使用者可以進行測試。這個外掛的本質是功能性外掛的集合,這讓它與其他提供非 WordPress 核心程式效能功能的外掛不同,因為其他效能外掛可能會需要 WordPress 核心程式不提供的功能。目前 Performance Lab 提供的效能功能會依照相關規則更新,例如功能整合至 WordPress 核心程式後,便會在外掛中移除,並且新版外掛不定期中加入新功能。

這個外掛可以使用於正式網站嗎?

依據前述的外掛主要目的,請將它視為包含各種效能功能的 Beta 測試版外掛。請注意,除非是標示為「實驗性功能」的功能,全部功能均已經過測試及確認,使用在正式網站應該沒有問題。與其他外掛相同,使用者均應自負使用風險。

使用者可以在何處提交外掛意見反應?

這個外掛作為 WordPress 核心程式的功能性外掛,我們非常希望、也非常感謝大家提供意見反應。使用者如果有任何建議或功能要求,可以在外掛的 GitHub 存放庫提出。如果對這個外掛有需要疑難排解協助或提出問題之處,請在外掛的技術支援論壇提出。

在何處可以回報安全性程式碼錯誤?

效能團隊及 WordPress 社群對安全性程式碼錯誤一向嚴陣以待,我們非常感謝使用者披露相關發現所付出的心力,並會盡全力解決使用者提出的問題。

如需回報安全性問題,請參考 WordPress HackerOne 計畫。

如何為這個外掛做出貢獻?

非常感謝各位的各種貢獻!請參考核心程式效能團隊手冊以進一步了解參與的方式。

Very much appreciated! Looking forward to some new features that solve everything.

Got the BIG warning that you’re breaking this plugin up into 3 different standalone plugins; because that’s what users want… 3 more plugins to install. I played along and installed WebP Uploads. Uninstalled Performance. The outcome: nothing. No menu whatsoever for Webp settings. Uploaded an image, no webp conversion. If your goal was to waste my time… mission accomplished.

hmm

pagespeed.web.dev says: Consider using the Performance Lab plug-in to automatically convert your JPEG uploads to the WebP format, if it is supported.But it’s not true, this plugin is not converting anything (maybe I am missing something), but yeah, useless for me
