Changing Debian 12 to Debian 13 with slow internet and Windows client issues
Changing Debian 12 to Debian 13 with slow internet and Windows client issues
Hello, following the server upgrade from Debian 12 to Debian 13, network performance on the 2.5G adapter noticeably decreased. Samba speeds range between 700-1000Mbit/s, while ZFS send and ZFS send +samba (via another vdev) are limited to about 1.8Gbit/s. On Debian 12 everything functioned perfectly; CPU usage appears higher than expected based on my observations.
Consider installing the Realtek driver directly from the official Realtek website rather than using the kernel-provided version.

It's strange. Speed works well copying from NAS to Windows PC via Samba, but fails when using the NAS's own Samba server on Windows PC.
Verified using SSD pool to Windows 10 PC with Linux Mint inside a VM on that system via bridged network. Attempted configuration with Set-SmbClientConfiguration -RequireSecuritySignature $false but failed. SMB.conf settings were adjusted accordingly. Unicode extensions enabled, wide links permitted, insecure links allowed.
After some trials: FTP runs smoothly at maximum speed without problems. Turning off encryption allows Samba to operate at full capacity: /etc/samba/smb.conf [global] server signing = disabled smb encrypt = disabled server multi channel support = no It appears: new encryption is required after upgrading from Debian 12 to 13 with Samba 4.17.12 to 4.22.6 OR encryption speed doesn't function on Debian 13 with Ryzen 5825u
I modified smb.conf with the following settings: global server signing disabled, smb encrypt required, and server smb3 encryption using AES-128-GCM. No need to look for alternatives—this seems to be the latest configuration after updating Debian 12 to Samba 4.17.12 and then to Debian 13 with Samba 4.22.6. If anyone has a better approach, I’d appreciate hearing about it.
