Yet another SLOW file transfer thread. krusader/windows/USB >> All slow.

[Mamaun]

Hi.

I'm new to unraid. I followed some spaceinvader's great guides to setup my server (adding krusader, plex with hd acceleration, qbitorrent, windows11 vm, some plugins...) and it's working very well... except for file transfers.

 

Here my setup:

• intel i3 10100 + 64GB ram
• 2x 10TB WD shuked HDD's (array)
• 2x 120GB Kingston SSD's (appdata/system cache)
• 1x 4tb WD Red SSD (media cache)
• 1x 500GB Sandisk (temp cache)
• 2x 8TB WD USB (unassigned) This were my main windows server media disks

 

• I've benchmarked my controller/disk with DiskSpeed and all seems ok (image is from Diskspeed)
• My USB disks can copy data at 180MBps in windows
• I don't have parity disk since the server main purpose is plex and I backup my important data manually
• I have disabled cache for any share from/to I'm copying data
• I have enabled/disabled turbo write.

 

When I try to transfer files from my Windows 10 server it tops at 60MB/S over ethernet

When I try to transfer files from unassigned devices usb to an user share, it tops at 50MBps (krusader)

When I try to transfer from /mnt/disks/USB to /mnt/disk/disk1 it gets even worse at 30MBps (krusader)

 

I don't know what I'm doing wrong.

Totally irrelevant since these are about how parity updates are done, and you said you don't have parity.

 

Attach diagnostics to your NEXT post in this thread.

What are you copying?  Large files or tons of small ones

Large files (>20GB) sequentially from single disk to single disk.

The speed cap is roughly the same over LAN or USB. No mater if I copy the files to a SSD user share, to a HDD or even if y copy to user0/SHARE.

The cpu is barely used (8%) and also the RAM (5%)

 

 

Oh. I can have two simultaneous transfers, one from windows via lan and other from unassigned usb device, both to the same array HDD and both cap at 40/50MBps

Give more info.

Something SO strange.

 

If f i copy files from windows to unraid, i get 40MBps. 

If I mount a remote and PULL same files with krusader i get 110MBps, maxing my Gigabit lan connection.
