Last published : Oct 20, 2026
The dual message queue feature allows the Session Recording Server to use a second MSMQ queue for processing data streams from VDAs. Enabling this feature can improve performance and scalability on multi-core Session Recording Servers, especially in environments with high recording traffic.

Enable the dual message queue

By default, this feature is disabled. To enable the dual message queue, complete the following steps:
  1. Log on to the VDA where the Session Recording Agent is installed.
  2. Open the Registry Editor.
  3. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\SmartAuditor\Agent.
  4. Create a DWORD value named MsmqDataQueueCount and set its value data to 2.
  5. Restart the Citrix Session Recording Agent service to make your changes take effect.

Disable the dual message queue

To disable the feature, either set the MsmqDataQueueCount value data to 1 or delete the registry value. A restart of the Citrix Session Recording Agent service is required for the change to take effect.
Note:
To use this feature, your Session Recording Server and Agent components must be version 2507 or later. Ensure you apply the registry change on all relevant VDAs for consistent performance enhancement.
