If a batch has many fields, a portion of them load before the batch is ready for you to correct it. The remaining fields automatically load in the background as you progress through the batch.

This means that you can start correcting a large batch before it is fully loading, reducing wait time.

Similarly, groups of fields are saved and sent to the server periodically. This enables you to correct fields at the same time as previous fields are saved, ensuring that a reasonable amount of data is sent between the Web browser and server when you process, suspend, and close a batch.
