The Windows client first tries to do the FSCTL_OFFLOAD_READ (which our btrfs module does support, but not the default ext4 module) and then falls back to regular SMB2 async read, ramping up from 32k initially to 1MB reads. I'm starting to think the problem is in your btrfs filesystem, not the Samba uring module. Before I spend more time on this I'...

I forgot to mention that when copied the files to a SSD, then I did not use any reflinks or hard links, just plain copies. > The Windows client first tries to do the FSCTL_OFFLOAD_READ > (which our btrfs module does support, but not the default > ext4 module) and then falls back to regular SMB2 async > read, ramping up from 32k initially to 1MB reads. Is this the "vfs module = btrfs". This was disabled too in the latest tests. > I'm starting to think the...

Hello, I am facing issues to keep samba share to be mapping in Windows 10 After computer start, and first login, the share is mounted correctly.
