Your Mac determines how each window and its contents should appear by collecting file information such as labels, tags, and other forms of metadata.
If a folder is sorted alphanumerically, the contents are displayed immediately, then the Finder collects and compares the rest of the folder's metadata.
Speed up browsing on network shares
To speed up SMB file browsing, you can prevent macOS from reading .DS_Store files on SMB shares. This makes the Finder use only basic information to immediately display each folder's contents in alphanumeric order. Use this Terminal command:
defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool TRUE
Then log out of your macOS account and log back in.
To reenable sorting, use this command:
defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool FALSE
