Benchmarking data:
A prototype for this solution on an
m7i.xlargeEC2 instance with 2,000 iterations shows an average 112.1 ms (22.02%) reduction of execution time for theaws --versioncommand (p < 0.0001), and an average 108 ms (18%) reduction of execution time for theaws sts get-caller-identitycommand (p < 0.0001).We expect similar numbers for most modeled commands. Commands that use more plugins at runtime will generally have higher execution time, since more plugins would be loaded.
