Opening a ZIP file on an SMB share takes a very long time.
I double-clicked a ZIP file on an SMB share in Gnome Files. It showed "Loading ... Please wait" for a very long time, potentially for ever, because I cancelled it after a while. If I do the same thing with Ark, it shows the file content instantly. If I copy the ZIP file to a local disk and then double-click it, File Roller opens the file instantly too.
