# Import batch size

The `polyfields_acf_options/import_batch_size` filter controls how many jobs are processed per scheduled async import batch.

## Default

Default value: `20`

## Behavior

Values lower than `1` are clamped to `1`. Lower values process fewer jobs per batch (slower but lighter per request). Higher values process more jobs per batch.
