I'm having a decent NestJs project. I'm using the Graphql CLI plugin and Prisma as ORM.
No matter how I start the project (start:dev, start, start:prod), there is a delay after loading all the modules and registering all the routes:

Here it was ~24s before Nest announces that it has successfully started. This delay does not happen on other NestJs projects I have seen.
Is it supposed to be like this? Any idea, where/how to further analyze what Nest is doing in these 20-30s?
