I opened up a PR with some benchmarks that I believe cuts down on Pulumi startup time for Typescript projects by over 50% (from 20s to 7s on a basic example using small CI executors): https://github.com/pulumi/pulumi/pull/9049 Some sample runs using pulumi v3.25.0 and using my fork on the same project can be found in the CI runs of my repo here: https://github.com/dmattia/pulumi-fork-perf-test/actions/runs/1899441732
