May I ask a few questions?
What is your base setup for your docker dev? PI? OS? Docker version (IO vs CE)?? RAM?
What is your docker image using for OS?
I would like to test. I have several Pi4s, but they are heavily in use.
I have a nice Lenovo IdeaPad III upgraded to 36GB RAM, 1 TB NVME, running Debian 11 (Bullseye) and docker.io. (It also has VirtualBox, and I am getting ready to install KVM (qemu) for other testing. I can easily add your image to my environment, I have a nice USB dongle for GPS and a USB2 to Ethernet adapter when needed.?
If you have any other suggestions for hardware or software to test, please let me know.
