You can adjust how MinIO balances the scanner performance with read/write operations using either the :envvar:`MINIO_SCANNER_SPEED` environment variable or the :mc-conf:`scanner speed <scanner.speed>` configuration setting.

|
|
|
.. end-scanner-speed-config

MinIO utilizes the scanner for :ref:`bucket replication <minio-bucket-replication>`, :ref:`site replication <minio-site-replication-overview>`, and :ref:`lifecycle management <minio-lifecycle-management>` tasks.

Valid values include:
|
|
|

.. list-table::

:stub-columns: 1

:widths: 30 70

|
|
|
* - ``fastest``
|
|
- Removes scanner wait on read/write latency, allowing the scanner to operate at full-speed and IOPS consumption.
|
|
This setting may result in reduced read and write performance.
|
|
|
|
* - ``fast``
|
|
- Sets a short scanner wait time on read/write latency, allowing the scanner to operate at a higher speed and IOPS consumption.
|
|
This setting may result in reduced read and write performance.
|
|
|
|
* - ``default``
|
|
- Sets a moderate scanner wait time on read/write latency, allowing the scanner to operate at a balanced speed and IOPS consumption.
|
|
This setting seeks to maintain read and write performance while allowing ongoing scanner activity.
|
|
|
|
* - ``slow``
|
|
- Sets a medium scanner wait time on read/write latency, where the scanner operates at a reduced speed and IOPS consumption.
|
|
This setting allows better read and write performance while reducing scanner performance.
|
|
|
|
May impact scanner-dependent features, such as lifecycle management and replication.
|
|
|
|
* - ``slowest``
|
|
- Sets a large scanner wait time on read/write latency, where the scanner operates at a substantially lower speed and IOPS consumption.
|
|
This setting prioritizes read and write operations at the potential cost of scanner operations.
|
|
|
|
May impact scanner-dependent features, such as lifecycle management and replication.
