Original author here. The two sentences right before what you quoted are helpful: "I’m not a Docker or Flask performance expert, and that’s not the goal of this exercise. To remedy this, I decided to bump the specs on my deployments. The general goal for this bakeoff is to get a best-case outcome for each of these architectures, rather than an apples-to-apples comparison of cost vs performance." I wasn't trying to squeeze out every ounce of performance and determine the minimum number of instances to handle 100 req/sec. I was trying to normalize across the three patterns as much as possible to see best-case performance. I didn't want resource constraints to be an excuse.
