Depending on your overall computing environment, using many custom properties can cause poor system performance, particularly when application links are enabled. By default, Meridian Enterprise synchronizes an empty custom property only if it contained a value and a user deleted that value. Each such property requires multiple operations to find the previous value of the property. If a document uses many custom properties, these operations can negatively affect system performance, particularly if network performance is not optimal or for batch operations with many documents.
To optimize the performance of application links with empty properties, see the description of the CheckBlankPropertiesAssigned setting in the BlueCielo Meridian Enterprise Configuration Guide and the following registry values that CheckBlankPropertiesAssigned overrides:
HKEY_CURRENT_USER\Software\Cyco\AutoManager Meridian\CurrentVersion\AMLink\Settings
HKEY_CURRENT_USER\Software\Cyco\AutoManager Meridian\CurrentVersion\AMDocUpdateUtl\Settings
