Performance improvements:
- Focus on network share performance
- Browsing a network share no longer makes Finder freeze or beachball while previews load, even over a slow VPN.
- Moving quickly through files on a network share no longer starts a full read for every file you pass.
- A file shown in both the Finder preview pane and the Quick Look window is no longer left stuck on "Loading…".
- Reopening a 4D file on a network share shows the Volumes slider right away.
