With `--parallel`, large tables and partitions start processing earlier, reducing the time spent waiting for large files after other parallel tasks complete. The improvement applies to `--backup`, `--prepare --incremental-dir`, `--copy-back`, `--move-back`, and `--decompress`. -* [PXB-3853](https://perconadev.atlassian.net/browse/PXB-3853): Improves incremental backups with page tracking by skipping unchanged page ranges between blocks of changed pages. This reduces unnecessary I/O, especially for large tablespaces, and keeps the amount of data read closer to the amount of changed data. +* [PXB-3853](https://perconadev.atlassian.net/browse/PXB-3853): Improves incremental backups with page tracking by skipping unchanged page ranges between blocks of changed pages.

This improves backup performance when changed pages are scattered. Backup contents and size remain unchanged. Set [`--page-tracking-merge-gap=0`](../xtrabackup-option-reference.md#page-tracking-merge-gap) to read each changed page separately.
