> SMB support in macOS remains slow and buggy to this day. I tried all combinations of server-side settings and obscure plist tweaks to make SMB navigation and search work as fast as they do on my Linux machine out of box before giving up. It is very obviously not a priority for their services revenue

That's where my thoughts went, too. I can make SMB "better" but not "great" usually, but it's annoying to have to look up and apply, and still have things not optimal. Just in case, IIRC I find this the most useful:

  defaults read com.apple.desktopservices DSDontWriteNetworkStores
  defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool TRUE

But surely some of the other tweaks that LLMs suggest may help, too.
