When you have thousands of files in the home folder, or use shared folder (UNC path/NAS path) as home folder, maybe the file listing will take a few seconds. Then you can speed up the listing process by the following steps:
1. Enable the option "Server > Settings > General Settings > Miscellaneous > Enable Directory List Cache".
2. If it is possible, enable the user option "Domain > Edit/Add an user > General > Show files/dirs with hidden attribute".
