for a startup time of 2.5 seconds, how many persisted classes are you using with hibernate?

This gives you another small improvement. Then, if you want some more, start up your virtual machine with the -Xverify:none flag to avoid bytecode verification and test startup time with your class file in a jar, this reduces file attribute verifications that are especially slow on ntfs filesystems (well, I guess the advantage is noticeable on any file system that's not otimized for the "many small files" pattern like the linux reisersfs filesystem). With these I can get my app startup time down to 2.5 seconds on a 1200 Mhz Duron with a quite old ntfs filesystem, and it's cpu bound now (the other hibernate initializations according to the profiler).
