### 比較B樹和LSM樹

儘管 B 樹實現通常比 LSM 樹實現更成熟,LSM 樹由於效能特徵也非常有趣。根據經驗,通常 LSM 樹的寫入速度更快,而 B 樹的讀取速度更快【23】。LSM 樹上的讀取通常比較慢,因為它們必須檢查幾種不同的資料結構和不同壓縮(Compaction)層級的 SSTables。
儘管 B 樹實現通常比 LSM 樹實現更成熟,LSM 樹由於其效能特徵的關係,仍然引起了不少關注。根據經驗,通常 LSM 樹的寫入速度更快,而 B 樹的讀取速度更快【23】。LSM 樹上的讀取通常比較慢,因為它們必須檢查幾種不同的資料結構和不同壓縮(Compaction)層級的 SSTables。

然而,基準測試的結果通常和工作負載的細節相關。你需要用你特有的工作負載來測試系統,以便進行有效的比較。在本節中,我們將簡要討論一些在衡量儲存引擎效能時值得考慮的事情。
