Anyone have advice on how to speed up my SMB configuration?
I have a usb3 hard drive connected to my RPI4, I enabled the cmdline.txt quirk for the USB hard drive.
transfer speeds seem to range between 1.2 and 3.8 MB/s to both the SDcard and the Hard drive.
The speed ranges when I try various smb.conf settings. 1.2 is at minimalist configuration.
3.8 MB/s is when I provide a config I found on the net.

Hi,
many thanks for your request. It might not 100% fitting but maybe you can have a look to this community tutorial

Hi !
Thanks for the tip, I switched my smb.conf to the one used by openmediavault that people report has high throughput in smb ith RPI4. It includes the socket options from the thread you recommended.
I now get 3.3 MB/s to the SDcard and 5.2 MB/s to the usb3 drive. the wired eth0 connection reports speed as 1000mb.
Any suggestions from here?

hmm I searched the web and did find quite some messages about slow samba performance. However there did not seems to be the one and only solution. Most of the time same recommendation are given but it did not fix it for everybody.
Just an update, It did seem to be the RPI4, I moved the SD card to a new pi4 and got fullspeed with SMB.
Thanks!
to bad that it seems your board. Can you share your final smb.conf file. I would like to have a check in my RPi4 to see how it behave.
