If the program is going to be running for that long anyways, why do you care? > Is startup time the only reason why the whole code is not jitted > immediately.. ? Even if the JVM put the code through the compiler right away, the resulting code wouldn't be very good because it will have not had time to profile code to apply the more powerful optimizations. It would be throwing all of that code away once it has had time to profile the code, so any time spent JITing the code before then is most likely not worth it.
