I've racked my brain with this one and I can't figure out what the issue is. I'm going to let you know, I'm a noob, but I know enough to be dangerous. I'v been playing with Unraid since Dec 2022 and I feel like I know a bunch from this piece of software. 

 

I have been plagued with slow transfer speeds for a while and I feel like I have done everything from across forums to speed them up. In the below example, I am copying a 2.34 GB file from one folder on my cache drive to another folder on the same drive. It takes 3.5 minutes to transfer from the same drive/device (not including mover piece). I have....

• Replaced all ethernet cables with CAT 6
• Added a cache SSD PCI-E drive
• Turbowrite mode / scheduling
  • At current, I have turned off turbo write as it doesn't make sense if most of the copying that I am doing is to the cache drive and invoke mover later on. Array drives are a mixed bag of speed (some 5400, some 7200), but I don't think that should make a difference in the example issue below. 
• Changed some shares to copy directly to the cache and invoke mover overnight to the array
  • Mover usually is not slow to do it's thing

 

 

Sometimes, when I restart my server, the speeds increase and go back to normal. Over the days, it slows back down. At my maximum, I've received 70-90 MBps (not megabits). Again, slows down over a few days and then I have to reboot it again. 

 

Is this just something that happens, or.... how can I triage this to remain consistent (as possible)? Restarting my server every day removes the purpose of having an always up server in the first place, you know?

 

Thanks for all the help. System diagnostics attached. Let me know what else you may need me to check and I will happily oblige!

Edit #1: Weird findings.....

Also, this looks wonky right??. This is AFTER I rebooted my server and did a copy of the same file. Keep in mind, this is just copying from one folder on the cache drive to another folder on the same cache drive. 

 

Edit #2: Ok.... what?

Even more interesting, here is what happens when I copy a Parallels VM file (roughly 30 GB) from a client computer (MacBook) to the server's cache drive. It was CRUISING! This is how I expect it to be all the time. 

 

Edit #3: Seems like a common issue?

What is the OS used? Copying a file from one device to another should not use the network, at least with Windows and Linux.
