Browse Source 
It is now 100MiB instead of 10MiB and no longer an app config,
but a system config option.

Adjust chunk size on Nextcloud side
-----------------------------------
For upload performance improvements in environments with high upload bandwidth, the server's upload chunk size may be adjusted::
sudo -u www-data php occ config:app:set files max_chunk_size --value 20971520
sudo -u www-data php occ config:system:set --type int --value 20971520 files.chunked_upload.max_size
Put in a value in bytes (in this example, 20MB). Set ``--value 0`` for no chunking at all.
Default is 10485760 (10 MiB).
Default is ``104857600`` (100 MiB).
.. note:: Changing ``max_chunk_size`` will not have any performance impact on files uploaded through File Drop shares as unauthenticated file uploads are not chunked.

We have a new setup warning to check if the memory reserved for APCu is high enough. If you see this warning, you should increase the memory reserved for APCu. You can do this by increasing the value of the ``apc.shm_size`` directive in your ``php.ini`` file. It is generally advised to review this value and increase it if necessary depending on your instance size.

Maximum chunk size
^^^^^^^^^^^^^^^^^^
We have adjusted the default maximum chunk size for big file uploading.
Previously it was set to 10MiB, it is now increased to 100MiB.
Also the configuration was moved from an app configuration to the system configuration (``config.php``).
If you set up a custom value previously the value will be automatically migrated to the system configuration during the update.
But if you need to set a new custom value you need now to use the system configuration, see also :ref:`files_configure_max_chunk_size`.
