[Slow SMB access times, general io vs SFTP]

Hi JorgeB,

 

I am on 6.11. I don't know if performance increased from 6.10 to 6.11... because the only time last year I worked remotely I was on 6.9 and it worked well.

[Slow SMB access times, general io vs SFTP]

I have also the same issue. It used ot be far better in 6.9.x. I can also confirm performance are worst since 6.10.x.

 

During holidays I have planned to work on my unraid (edit videos, photos etc...) Last time I did it was in july, and I was able to work on my unraid easely. Last week was a nightmare. I had to move files on my local computer to just be able to work. A simple search on 12TB of files (big files... 1GB minimum), can take up to 2mn. Editing is just not possible. It always used ot be slower remotely... but this time it is just a nightmare. 

 

I have also notice is a drop in performance when I do multitask on the same share. For example, if I have a download (direct torrent download on unraid with qbittorent docker) + access files on the same driver with SMB... Performance drop is clearly amazing.... from 110MB/s to 20-30MB/s.... just because I use SMB at the same time.

• Watching a movie with local SMB on vlc + torrent direct download => 30Mb/s download speed
• Watching a movie with local Plex (http) + torrent direct download => 110Mb/s download speed.

 

I assume SMB use so many IOs that it struggles completely the server.

 

FYI, I am the only user of my unraid... so I can imagine with dozens and dozens of users, it is just not usable at all.

 

Of course, there is no hardware bottleneck on my server. Intel I7 10k, 512 nvme ssd cache + 4 drives 4TB xfs on sata. I drive for parity. I assume it is a standard low configuration used by most people for home server.

 

Let me know if I can help (tests, etc...). Do not hesitate.
