Finder is very slow in showing the content of server shared folders I'm accessing a Windows File Sharing folder on my home server in Finder on my Mac (OS X 10.7.2) using the SMB protocol. When I'm navigating through the folders, sometimes (most of the time) I have to wait up to 10 seconds until I can see the list of files in the selected folder. Also, there is no visual clue that Finder is fetching the file list, so the first time I got this behavior in Mac OS X Lion, I was thinking the folder was empty.

Even worse, when I'm copying some large files to the server, Finder is delaying the process of getting the file list more or less until the copying is finished.

Is this something I can fix? Or is it a known bug in the Finder/SMB protocol implementation?
In finder make sure you have status bar showing under view options.  You should see a spinning gif animation while the folder is loading.  If you have visited the folder recently the file list should be cached.
