Hi all, I have an issue where whether I am doing a SMB file transfer, streaming from Unraid to a media playback device via SMB, or even running a speed test via the OpenSpeed test, network traffic drops to 0% briefly and recovers every 40 seconds (ruling out that it is SMB related).
This is an example of when I was doing a large single file transfer to illustrate the issue. The main reason I am chasing this down is because my media players have small buffers so these drops cause the media playback to stall even at much lower data rates.
Things I have tried:
Moved my docker.img off of the spinning disk array to my SSD cache
Disabled the Docker service entirely to avoid any extra R/Ws being done to the disks
Disabled NIC Offload in the Tips and Tweaks Plugin
Adjusted Disk Cache settings to the below but also tried various values
vm.dirty_background_ratio at 2%
vm.dirty_ratio to 4%
Transferring data from various different physical disks including off of cache SSD
Hardware info:
i9-9900K with 64GB of RAM
LSI 9211-8i SAS controller
7x 18TB WD Red Pros (all SMART tests pass and the drives are less than a year old)
2 drives are parity
QNAP QXG-10G1T 10GbE NIC w/ Marvell AQtion AQC107 controller (used in previous NAS which did not exhibit this issue)
Main PC and Unraid server on the same Ubiquiti Flex-XG 10GbE switch
If anyone has any ideas of other things to try, I am all ears and greatly appreciate any potential leads!
