I'm a new unraid user. Have been using it for a week. I'm evaluating it at the moment, to see if it will suit my usage. I love everything about unraid so far. But one thing has me bugged beyond anything, Hyper slow transfer speeds. (2 MB/s over wifi, 35 MB/s over cat5e ethernet cable. Details below) This is my Unraid configuration latest version. 6.3.1 3 disk array (1 parity) data disks are new. bought last year. but never used until last week parity disk also new. bought last year. but never used until last week 1 ssd cache. bought last year but never used until last week Gigabit LAN (or atleast thats what the networking section on the main tab tells me) 5 network interfaces (they were bonded by default. but I disabled bonding and disabled all interfaces except eth0. So eth1, eth2, eth3 and eth4 are disabled. Bridging is enabled) This is my Local Network configuration Unraid connected to router via cat5e cables Test ubuntu machine connected to router via wifi After testing on wifi the same ubuntu machine was connected to router via cat5e cable with wifi disabled to test speeds on cable Test mac laptop connected to router via wifi Router is AC1750 TpLink. Supports gigabit speeds.(http://www.tp-link.com/us/products/details/cat-9_Archer-C7.html#specifications) All wifi used is IEEE 802.11ac/n/a 5GHz and NOT IEEE 802.11b/g/n 2.4GHz. I mention this because AC1750 is dual band. But b/g/n is disabled cos it's slow as per spec Test Setup I have a smb share called media on Unraid. Within that I have another folder called Movies. The "media" smb share is configured to use the SSD cache The "media" smb share is "secured" Scenario 1 (Ubuntu laptop over wifi) Transfer movie from laptop to unraid share "media" Speed is 2MB/s. Grindingly slow Scenario 2 (Ubuntu laptop over ethernet) Transfer movie from laptop to unraid share "media" Speed is 35MB/s. Slow. Scenario 1 (Mac laptop over wifi) Transfer movie from laptop to unraid share "media" Speed is 2MB/s. Grindingly slow Can someone please tell me how I might improve the speeds? If you need a zip of the diagnostic please let me know. I can run the tests again and send the diagnostics over. More over, I've only mentioned the write tests (writing to unraid box). If read tests are required, let me know. Thanks

Thanks for the video. Cleared up many things about how docker works in Unraid. Much appreciated.

When you say, the docker.img file is where the images are stored, does that mean "docker.img" gets mounted like a virtual block device?

I'm trying to understand unraids implementation of docker. Can someone please tell me what is the docker.img file? I see it in my cache device. A prior search on the forums seems to suggest that the docker.img file is a raw virtual block device that's stored in the cache device and gets mounted when docker applications are used/installed. But all threads discussing this, were either inconclusive or confusing. So my question is what exactly is the docker.img file and how does unraid use it to provision docker applications? Is it used as a virtual block device to store docker images and containers? Or is it used in some other completely different way? There are quite a few guides discussing how to install/configure docker apps. But none of them seem to address, what the docker.img file actually is! Any pointers to other guides or any other insight about this would be much appreciated.
