Synology Volume 卷使用率一直是100%

经过SMB即windows共享访问Synology NAS很是慢，到全部文件显示要几分钟时间，同时文件上传也变慢，打开Resource Monitor显示Volume Utilization几乎一直处于100%的状态，网络多方查找无解，问了Synology Support，他们说这个高使用率只说明机器一直有读写而不表明影响性能。

Why is volume utilization always so high in Resource Monitor?

A high percentage of volume utilization does not necessarily represent a problem. The value refers to the percentage of access rate within a designated time frame.

For instance, if a volume is accessed for five seconds within 10 seconds, its volume utilization would be 50%. If it is accessed throughout the entire 10 seconds, the percentage would be 100%.

This simply indicates processing data I/O rather than heavy loading on your Synology NAS.

本身闷着头查了几天，看到27TB的磁盘容量也只用了不到4T而已，而后脑子闪过一个场面：莫非跟以前linux服务器同样，是由于小文件太多致使 inode空间不足继而使服务器运行变慢？目前NAS的存储的小文件达到千万级别，再联系这个NAS后台也是Linux，我估计极有可能，因而尝试将文件转移，花了几天时间，而后再观察这个volume utilization, 终于变回正常了。看来对个人状况，磁盘空间不是问题，小文件数量巨大才是问题，所以须要把文件存储方式作出修改，我须要把读写分离才行。
