I'm an Eng for a startup using Rails, MySQL, ... Next.js.

The only problems we've had is slow performance of Docker for us with our databases. So much so, we've moved those out of Docker and back to the native. Performance is easily 6x faster. MySQL was also a headache because finding a MySQL 5.7 official Docker container didn't exist for ARM so we needed to use the slow emulation through qemu.

We also have a CLI dev tool that is written in Python and distributed in Docker (x86) which has also been slow. Not enough time to build ARM based Docker image.
