If there is a consistent connection failure between the agent machine and App Volumes Manager, the end-user login time can be reduced by setting the registry value of RetryStartupRequestFrequency parameter to 0 in the agent base image.

The parameter’s registry value indicates the interval in seconds between retries. Setting the value to zero stops the agent machine from retrying the communication.
KeyName HKLM\SYSTEM\CurrentControlSet\Services\svservice\Parameters
ValueName RetryStartupRequestFrequency
ValueType DWORD
ValueData 0

After setting the registry value, to deploy the base image in the Horizon pool, you must restart the agent machine.
