    20  * '''without''' NFS tunning, kernel io scheduler = '''default'''[[BR]]
     20 * 設定不同的 kernel i/o scheduler，根據 lustre 官方文件 3-8 頁所描述，最適合 Lustre 的 kernel i/o scheduler 為 deadline。[[BR]]
     21[[Image(Lustre with diff kernel_scheduler.PNG)]]
     22 * 在 Create/Delete檔案方面，則是以 as 有較佳的表現。
     23[[Image(Lustre create with diff kernel_scheduler.PNG)]]
     24 * 當多個 Client 同時存取時，lustre file system 的效能有顯著的提升。
