I really don't struggle that much with cold starts on Node.js/Lambda, and I don't do anything special, my build commands look like:

    esbuild src/handler.ts --bundle --external:@aws-lambda-powertools --external:@aws-sdk --minify --outfile=dist/handler.js --platform=node --sourcemap --target=es2022 --tree-shaking=true

Sure, but the approach mentioned here benchmarks with median performance of 16ms. 100ms isn’t great especially if it’s only one part of everything that needs to happen
