I have Java apps that are up and running in well under a second. It's reflection-heavy frameworks that drag out the startup - avoid those, and Java can be pretty quick.
Maybe never quick enough to use in a CGI style environment, or for command-line tools you want to call from a loop in a script (at least, without AOT). But plenty quick enough for any normal server-side use.
