I'd really appreciate any useful information that might allow the use of protected mode, but with reasonably good performance in the following scenario:
Environment:
- Windows 7 desktops with Adobe Reader XI
- AppData is redirected to users' home folders
- Desktops (5 - 10 in most cases) across a ~10 Mbps MPLS link from server hosting fome folder and the PDF docs being accessed.
- Protected Mode Enabled (as recommended)
Symptom:
- It takes an inordinate amount of time (20 - 30 seconds) to open a tiny (100KB file) from a remote file server. By comparison an Excel spreadsheet of similar size opens in 2 - 3 Seconds.
Temporary Workarounds (either results in SUBSTANTIALLY better (and acceptable) performance):
- Disable Protected Mode (for obvious reasons, we'd like to have this feature enabled)
- Disable Appdata redirection (for many other reasons, Appdata redirection makes sense for our environment)
Other notes:
A network trace shows a large amount of SMB/CIFS traffic (5000 - 6000 packets) to/from the AppData folder when appdata is redirected to the users' home folders.
One thought I had was whether or not there is a means to direct an app to use AppData\Local instead of Appdata\Roaming, or if there is a means to direct Adobe reader to use an entirely different (and local to the OS) folder for whatever it needs appdata for when in protected Mode.
Any suggestions that don't include the workarounds already described are welcome. Thanks!
