this is naive

"just as well"? lmao sure i guess i could just manually set up the environment and have differences from what im hoping to use in productio

> 1GiB machine can run a lot of server software,

this is naive

it really depends if you're crapping out some basic web app versus doing something that's actually complicated and has a need for higher performance than synchronous web calls :)

in addition, my mq pays attention to memory pressure and tunes its flow control based on that. so i have a test harness that tests both conditions to ensure that some of my backoff logic works

> if RAM is not wasted on having duplicate OSes on one machine.

this is naive

that's not how docker works...
