Your Mac determines how each window and its contents should appear by collecting file information such as labels, tags and other forms of metadata.
In macOS Sierra 10.12 and earlier, your Mac gathers all metadata for the files in a folder, compares it to the folder's .DS_Store file and then displays the folder's contents. In macOS High Sierra 10.13 and later, this behaviour is changed slightly: 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 re-enable sorting, use this command:
defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool FALSE
