Depends what your server is doing, java app binded to http port will take probably same amount of time.

My dropwizard server contains almost all possible batteries: ssl, logging, http filters, static content, metrics, DB connection pooling, static content serving, all kinds of URL parameter parsing and URL routing, DI framework, ORM, thread pooling. I think it just inspects and initializes all this data structures in memory, load libraries and classes, etc.
