The JVM startup time is very small nowadays (seriously, write a Hello World! class in Java to test it if you don't believe me). The culprit is probably JRuby's startup time (and maybe the Truffle + Graal version of JRuby is even slower to startup than regular JRuby).

Yeah, I'm oversimplifying. However, compared to MRI, the JVM starts up quite slowly. Pile on JRuby et al and you end up with an even slower time to go. I think the JRuby people have been very focused on feature parity, interop, and bug fixes so I'm not sure they've prioritized startup time. For now, I'm happy with that, I don't restart my app that often, basically only on deploys.

Startup is slow right now, but there is a project underway at Oracle Labs which will reduce it to a similar level as MRI.
