it's a low default to work with server limits, I would keep it that way tbh. The config can always be changed by the admin who knwis their environment.

@blizzz Do we have evidence that 10 MB is a reasonable server limit?
I see countless of threads of people on internet complaining that their uploads are slow. But they don't have the necessary technical expertise to link it to chunk size.

Why not set the default to something like 1 GB and let people with rare server limits change the configuration?

When admins can configure their webserver and PHP, they can also increase the chunk size. When other admins have only limited access and need to leave with default values by their hoster they cannot and might not even have access to the occ utility.

@blizzz What would you think about setting the default to auto and calling this function to determine the max upload size?

<?php
$default_max_chunk_size = ini_get('upload_max_filesize');

if ($default_max_chunk_size === false) {
	$default_max_chunk_size = 10 * 1024 * 1024;
}

This wouldn't work for misconfigured apache/nginx servers though.
