Disable icon previews on NFS mounts from the server

Hi,

When browsing a NFS3 mount in Finder implicit read requests against the first and last offsets of each file are made. This causes issues when browsing larger directories where this specific NFS-server is single threaded and thus can only process one request at a time.

Since this NFS-server is accessed by clients out of our control we would like to be able to disable this behaviour from the server. We've found that it can be disabled on the client by deselecting the "Show Icon Preview" checkbox under Finder View Options.

After some googling we've seen references to some "magic" finder files more specifically:

  • .ql_disablecache
  • .ql_disablethumbnails

We've tried servering these files in the root of the mount with a 0 byte content but to no effect. Is there any documentation available about these files or do anyone know if how this could be solved in any other way without requiring the client to make configuration changes in Finder?

Thanks
