Workaround for the Kernel Panic with M2 Macs: File Sharing via 10 Gigabit Ethernet

re: Bleeding Edge Computing: In Less than 24 hours, macOS Ventura Seemingly Self Destructs

I didn’t much like the idea of converting my 8TB OWC Thunderblade SSD from SoftRAID to Apple Disk Utility format, so I decided on another course which sidesteps the entire issue, albeit slowing performance to ~1.1GB/sec.

File sharing with 10 gigabit ethernet

File sharing over 10 gigabit ethernet gets the job done nicely. Regular ethernet also works, but 1150 MB/sec is 10X faster than 115 MB/sec.

Direct connection via Cat 6 ethernet cable @AMAZON from 2023 Mac Pro M2 Ultra to 2019 iMac 5K.
OWC Thunderbolt 3 10G Ethernet Adapter on the iMac to make 10 gigabit possible.
Configure Jumbo frames for better efficiency.

Connect from one Mac to the other via File Sharing.

Performance

Performance is at or near the absolute limit of 10 gigabit, as IntegrityChecker Java proves*:

Configuration in macOS Ventura

Configure a non-routable LAN-local subnet not otherwise in use eg 10.0.0.x or 192.168.1.x. This will be a 2nd local LAN for use only between the two machines.

Configuration in macOS Monterey

Same idea.
