When I upload files from Win11 to my server using SMB I can only reach about 80MB/s no matter if the file is stored on the cache pool (2x WD SN700 NVMEs) or is already on the disk(s).

Sometimes tranfer will drop to below 70MB/s.

 

 

Uploading is fine and I can max out my 1000/1000 (Mbps) connection with about 110MB/s.

 

How can I improve the reading performance?

Thank you.

Tests seem to be fine in both directions.

 

From server to Win11:

 

From Win11 to server:

Try with a with a different client computer if available.

Tested with dualboot Manjaro and it looks fine:

 

 

So it is related to Win11.

Any idea how to improve the performance when using Win11?

Thank you.

Disable any AV solution, if that doesn't help probably easiest to just do a new install.
