If you would like to preload the index with existing orders and/or profiles, perform the following steps:

Enhancing Performance of Bulk Loads

In environments where you are working with large data volumes, you can enhance the performance of the bulkLoad indexing process. By default, the /atg/commerce/search/OrderOutputConfig/
is set to 4, which is equal to twenty thousand orders retrieved for batch processing. This results in a high number of unconstrained executions of the SQL query used to initiate the bulkLoad indexing process.

To reduce the number of unconstrained SQL query requests and improve bulkLoad performance, increase the threadedItemQueueBatchSize parameter to no more than 20. Setting the value higher than 20 could result in Out of Memory exceptions and database time out exceptions.
