If you have users waiting for cold starts (e.g. AWS Lambda without "provisioned concurrency"), the JVM start-up still is problematic, despite all the great improvements that recently have been made (OpenJDK 15 again got some nice improvements, e.g. related to AppCDS). I'm discussing this in this post about a Serverless blog search I've built with Quarkus and Lambda: morling.dev/blog/how-i-built-a-serverless-search-for-my-blog/. Disclaimer: working at Red Hat, contributing to Quarkus a bit.
