To those with problems that the upload freezes some seconds (like 10MB limitations like @gcuelec ) there is already a threath about this.
Uploads "chug" in 10mb segments?
The other thing is the upload speed for example on raspberry pi, that uses only one thread with php-fpm, people say that using php-fpm7.4 has improved the upload speed to 20mb/s or like that. Anyw, i would recommend to use scp to upload your things cause is not limited.
Hope this answer help u all.
