JVM is the slowest runtime in terms of startup. But it does run way faster once it has run for enough time and has profiled and optimized a good portion of your application. In most cases where Java is used on the server, it is expected to startup once and continue running for a long time and host multiple applications. In this JVM's startup becomes a non-issue and its optimizations become a huge benefit.
