New hardware, stuttering video stream via SMB

[Brian Yuen]

Hello all,

I've been using Unraid for almost a year now from old parts (AMD A10-7850K 3.7 GHz, Gigabyte GA-F2A88XN motherboard). I recently upgraded to newer hardware (13th Gen Intel i3) and kept the same unraid configuration and drives. Even before the upgrade, I had no complaints.... I just wanted the machine to be more power efficient and utilize Intel Quick Sync for hardware transcoding in Plex.

 

The upgrade went smoothly, Plex is now hardware transcoding. However, streaming videos via SMB is now not a great experience. I'm using a Meta Quest 2 to view 6k videos (10-18gb videos) with the Skybox video player. This used to work on my old hardware from 2014 and streamed smoothly... but not brand new hardware? All network settings are exactly the same. I'm wondering if this is an SMB issue, or possibly something in the new motherboard BIOS?

 

Any help would be great.

Following this, as I'm having a very similar issue. My new server I just built is on the opposite side of yours, much MUCH more (thats not to brag, its to point out that something is really up, and I'm not sure what either). I ran openspeedtest and the 2.5gbps switch is almost fully saturated between my PC and the Unraid box. Plex buffers, but watching the same video through MPC-BE from the SMB share, it is disgusting the level of stutter/buffer. So I'm eager to see what insights others might have, and glad to know I'm not alone in it.

 

Just tried to transfer a file from the SMB to my desktop, 9.9mb/s lmao... what in the heck...

 

@Brian Yuenare you by chance doing any I/O intensive operations on the UNRAID in the background. I figured my hardware would be up to snuff to handle all that I was doing... and apparently not. Its some downloading docker apps that are basically crushing the hard drive's ability to do much of anything.

Thanks. I am not. I had both the dashboard and the main tab open to check if anything was going on, and nothing was out of the ordinary.

There may be some problems with the 13th GEN processors.  Google     unraid.net 13th Gen Intel problem   and go through the threads.
