With Cloud Run gen1 and Go apps, we're getting sub-1s start times. With Node.js or Python, start times are dismal, ie. 5s or more. That's 5-10 times slower than starting these services locally. Although I haven't checked this rigorously, it seems that reading many files is very slow on Cloud Run, and the large number of imports these apps have don't play well with Cloud Run. With Gen.2, for a Go app, startup time went from 500ms to 3-4s, which is more than I expected, and support wasn't able to tell us whether that's normal. That's kind of a shame because otherwise it's one of the best services I used.
