macOS will delay disk and other input/output operations for background tasks like backing up. Is there any point in disabling that in an Apple silicon Mac to make backups faster?
I/O
It’s well known that writing Time Machine backups to storage is throttled to slow them down. What’s the point of using faster SSDs that are more expensive if macOS stops them from being fast
Can you get Time Machine to back up faster by turning I/O throttling off? If so, it this something to do only for large backups, or can it be set as the default? Does it also affect other background processes?
Is it overhead from sandboxing, the file system, the throttling of I/O, or the limitations of the Efficiency cores? Is there anything a user can do?
