iPhone 15 Pro Max iPhone 15 PM very slow wired backup

Well... just started mine/320GB on the phone to my M2 Max 16" MBP on Ventura in preparation of getting a replacement phone. Connected via TB4 cable and I hope it does not go that slow.
Ok... maxing out at around 75 MB/s this is some absolute horse 💩 . Other than not being on Sonoma yet, there is no excuse for 2 FLAGSHIP Apple devices working so far below claimed specs.
Haha... yep. Guess I am infamous now. I am doing this proactively. Starting a chat with Apple Support. I only live like 7 min from an Apple Store, just trying to multi-task with work at the moment.
the 320GB backup took about 90 minutes. AppleSupport chat was like trying to discuss calculus with someone equipped to teach me my ABCs, so I just made a Genius Bar appointment for tomorrow.
I upgraded the phone to 17.0.3 with no changes in my burn-in or data speed transfer. Might need to read a bit more about the Sonoma bugs before I try and upgrade that tonight.
I'll have to check that out. Would be sad if a 3rd party app worked more efficiently at such core Apple functionality.
I didn't see any difference with iPhone backup/restore speeds on my Pro Max when I was restoring it from my Mac. This was with the Apple Thunderbolt 3 USB-C Cable.
It appears they didn't make any improvements there, despite USB-C and 10Gbps unfortunately.

no, in my scenario the firmware restore in dfu went a lot faster from ipsw and usb-c cable.
but backup speed is totally terrible
Not having super-fast backups is at least somewhat understandable, given that these backups end up being broken up into a bunch of little files, encrypted, etc., so there's overhead. But it doesn't sound like there's a noticeable improvement (if any at all), which is quite disappointing.
I have not yet done a backup, but I did do a test transfer of about 1.6gb of video files (so, somewhat large files, not a bunch of tiny ones). Connected with a cable that gives USB2 speeds, it took 53 seconds, with the transfer speed appearing to be about 30-32MB/s. Connected with a Thunderbolt cable, with System Profiler showing a 10Gb/s connection, those same files took about 15 seconds to copy, at about 110-112MB/s.
Perhaps this situation is similar to those common USB3 flash drives, which might connect at 5Gb/s but the actual transfer speed is limited by the flash memory controller, thermal constraints, etc.
