You can write your code on a nice fast machine. A dev machine should be as fast as possible. Those devs with their big fast machines should be required to run and test on much lower spec machines though. Testing only in a VM on a beefy dev box leads to terribly performing software on customer machines. There's a multitude of performance problems that only come up when a system starts paging to disk, a machine has a HDD, or a CPU gets maxed out. These issues will be completely occulted on a dev machine with tons of RAM, 16 cores, and an NVMe disk. Far too many developers have the beefy dev box with no requirements to test on more prosaic configurations. Even limiting a VM's CPU and memory isn't a good environment for performance testing because it's still faster than actual low end hardware.
