QNAP’s response to online community discussions regarding abnormal file system performance

[Symptom Observation]
When the volume is filled with large amount of data, the Turbo NAS might encounter sudden write performance drop. After removing some files to free out available free volume space, the performance could become normal again.

[Analysis]
In QNAP Turbo NAS firmware version from v3.2 to v3.6, it might take a long time to find the free blocks to write files when the large amount of files are stored in the Turbo NAS. Therefore, users could encounter slow write performance under this circumstance.

[Solution]
Users who encounter similar scenarios are strongly advised to upgrade to the Turbo NAS firmware 3.7.1 or a later versions. According to QNAP lab’s verifications, upgrading to the new firmware versions could solve the abnormal write performance.
In real life operations, other known facts could also cause slow performance, including bad blocks on the hard drives, very little free space left on the disk volume, or fragmented data.
If upgrading to the new firmware versions does not help, please send us an email at [performance at qnap dot com ] or contact QNAP Support. We will be pleased to assist you.
