File transfer speeds dropped after upgrade to QTS 4.5.3.16 70(20210515)

Post by DataMeister »

My network file transfer speeds seem to have dropped after an upgrade from QTS v4.5.2.1594(20210302) to v4.5.3.16 70(20210515).

Previously, on a 4-disk RAID 5, when transferring large files I would easily max out the 1Gb network connection and show about 112 MB/s in the Windows file transfer dialog. Even when the system was multi-tasking I could still get 70-90 MB/s.

However, now every single large transfer will see a couple seconds of around 112 MB/s and then it drops down to under 30 MB/s.

Once the transfer speed drops down the HDD chatter is noticeable. It's like the HDDs are fragmented or something.

Has anyone else seen this on v4.5.3.16?

I was just having issues myself with file copy from windows 10 having - absolutely woeful speeds over a 10Gbe link to my NAS (no issues from my Linux partition). In my case disabling AutoTuning caused my speeds to jump from between 30-70MB/s to almost 450-500MB/s simply using drag and drop.

From an elevated command prompt:

Disable:

Code: Select all

netsh int tcp set global autotuninglevel=disable
Enable:

Code: Select all

netsh int tcp set global autotuninglevel=normal
Worth a try ¯\_(ツ)_/¯
