In the future, I plan to re-enable server multi channel support. Server string = %h server (Samba 4.13.14, Ubuntu 21.10) # Next line experimental until 4.15 - macOS clients support multi-channel SMB3 Passwd chat = '*New Password:*' %n '*Reenter New Password:*' %n '*Password changed.*' Panic action = /usr/share/samba/panic-action %d # Next 2 lines defer mDNS config to Avahi (better for icon and Time Machine) # Enable extended attributes (requires streams_xattr) # Next line requires catia (needed if no Windows clients?) I also disable a lot in Samba that I don't need: I have been using the following settings on my macOS clients (/etc/nf) for a while: signing_required = no This helps improve performance quite a bit however, prior to Samba 4.15, setting server multi channel support = Yes in your /etc/samba/smb.conf will result in panics each time a client with a mounted share reboots. Valid users = implementation of SMB3 on macOS Big Sur and later has multichannel support ( see this article). Recycle:excludedir = /recycle,/tmp,/temp,/TMP,/TEMP

Recycle:repository = /tank/storage/.recycle/%U Vfs objects = recycle acl_xattr catia fruit streams_xattr Idmap config MYDOMAIN:range = 10000-20000 Idmap config MYDOMAIN:schema_mode = rfc2307 When connecting to a share however, I am only getting 150-300 MB/s read/write performance. Since I recently got a new Mac Pro (running Catalina 10.15.2), I connected it using 10 GBit Ethernet to my Debian 10 / Proxmox server.
