Drupal performance (in DrupalCamp Taipei)
- 1. Drupal 超速指引 How to Speed Up Drupal Jimmy Huang 2011 Drupalcamp Taipei email: Jimmy at netivism.com.tw blog: jimmyhub.net
- 2. 高效能 Drupal 策略 小比大好，少比多好，瘦比胖好 不該出現的不要出現 不需裝的不要裝 不需即時運算的就快取 記憶體比資料庫好 資料庫比檔案好
- 3. 如何擬定效能改善方針 瓶頸在哪裡？ 慢再哪裡？ CPU / 記憶體 / 流量？ 哪個頁面發生這個問題？ 慢再何時？ 檢測瓶頸 CPU : 確認是 Apache 還是 MySQL 記憶體 : 確認沒有用到 Swap 磁區 流量 : 確認連線場所網路順暢 頁面 : 確認某些頁面特別久
- 4. 如何擬定效能改善方針 ( 續 ) 哪個網頁特別龜？ 登入時瀏覽和登出時瀏覽的差異？ 租用哪家 Server ？有權限做 Server 調整？ 每日造訪頁數 （ awstats / google analytics ） ? 很多人看？還是很多爬蟲？
- 5. 如何擬定效能改善方針 ( 續 ) 安裝模組 ex. memcache, boost, csstidy … 調整 Server ex. Apache MaxClients 數值 ex. Mod Deflate 調整 Drupal 設定 根據檢測出來的頁面，調整對應設定 調整程式碼 非不得已，自行開發模組，再調整程式碼
- 6. 在 Drupal 如何檢測效能 Devel 觀察記憶體 / 頁面產生速度 Devel 蒐集 Database 使用的狀況 分析 Query 問題、來源 調整出問題之 Views / Panels / 程式碼
- 7. 在 Drupal 如何檢測效能 ( 續 ) garland, system, block, dblog, filter, menu, node, taxonomy, user, content, date, date_api, date_repeat, date_timezone, number, optionwidgets, text, feeds, feeds_ui, feeds_xpathparser, ctools, job_scheduler, devel, views, views_ui

- 19. 實戰 – 快取技術 Drupal 快取方式 Menu , Form, Page, Variables, Content, Language … 快取技術 Drupal 內建整頁 HTML 快取 Views / Panels 模組快取 Boost 模組
- 20. Drupal 頁面快取
- 21. Views 快取
- 22. Panel 快取
- 23. Boost 快取
- 24. 實戰 – 記憶體快取 為何把快取放進記憶體？ 建立 Database 連線緩慢 MySQL 的效能不足 Database 新增、刪除的動作比記憶體慢 如何做？ 安裝 memcached 安裝 php-memcache 安裝 drupal memcache
