Dolphin slow to read server data / slowness after Windows 10 upgrade

Last Updated: February 18th, 2020Published On: January 22nd, 2020By

Windows 10 Update v1803 may cause performance issues with your Dolphin system. Specifically, it can cause a delay with Windows reading the Dolphin data on your server. This can trickle down to any Dolphin process that accesses the data including, but not limited to:

  • Launching Dolphin Imaging
  • Patient Lookup in Dolphin Imaging
  • Capturing Images
  • Saving Documents into the Document Organizer in Dolphin Management
  • Opening a Patient Document folder
  • Microsoft RDP Protocols for those that use Terminal Servers and Microsoft remote app where windows may popup in the background

If you are experiencing any of these issues, read below for instructions on how to fix it. Note: Do NOT apply this fix if you are NOT experiencing any of the above issues.

Be sure to back up the Windows registry before performing any of these steps. (Visit here for directions on how to do this.) We recommend you contact your local IT person for assistance on the changes below.

  1. For slow performance, disable SMB client-side caching on the local workstation. (Issues A – E)
    • On your keyboard, press the Windows logo key (bottom left of your key board) + R key combination and in the Run dialog box type regedit and press Enter to access the Registry Editor.
    • Go to HKEY_LOCAL_MACHINE and navigate to System\CurrentControlSet\Services\Lanmanworkstation\Parameters
    • Create a new DWORD value for DirectoryCacheLifetime
    • Right-Click in the open space > New > DWORD (32-bit) Value > Name DirectoryCacheLifetime
  2. For issues with Microsoft RDP and Remote App Connections and windows/prompts appearing in the background (Issue F).

Change the following group policy to “Disabled:” Computer Configuration/Policies/Admin Templates/Windows Components/Remote Desktop Services/Remote Desktop Session Host/Remote Session Environment: Use advanced RemoteFX graphics for RemoteApp – Disabled.

Note: You can do this either locally or via GPO in an Active Directory environment on all Terminal Servers/Remote Session Hosts.
