Monitoring latency: Cloudflare Workers vs Fly vs Koyeb vs Railway vs Render

What struck me as odd here is how slow everything (apart from Cloudflare) is. I remember striving for a <=200ms P90 latency on API responses while building a large-scale platform about a decade ago; however, it now seems like that would get trumped by boot times of these platforms. Have we gone backwards in terms of speed? Am I misremembering something?
