We have a Ruby application running on Ubuntu x86 Linux. Development is done
locally on the developer's machines using Vagrant managed VirtualBox VMs. File
synchronization is handled by vagrant rsync. NFS and the built in VirtualBox
file sync were not performant.
By coincidence all developers use Macs – they choose their hardware. And they wanted to use new Apple Silicon (Arm 64) machines. These new machines can not emulate X86 hardware with reasonable performance.
