Update: The ADM file can now be downloaded here.
I recently came across a post in the Windows Server Performance Team's blog that lists several registry values which can be used to tune Explorer's SMB performance by modifying the following:
- Searches for Desktop.ini files used for folder customization
- Periodic refreshes of folder contents
- Searches for supporting library (.dll) files
- Individual file details and attributes pulled for each file
- Thumbnail extraction
