FWIW, I'm interested in any and all tech for improving startup of JVM-based stuff. Current Hotspot simply does not start fast enough to be used for command-line utilities, even though it has been improved. It's not because of the boot-time stuff anymore, but now cold performance comes into play. For commands that only run for a couple seconds, running cold (at many times slower than hot) just isn't acceptable. fork is one way to address that, by keeping a "hot" VM and spawning instances of it, but JVMs that save their jit products (like Excelsior JET) do an excellent job too (once primed. JET starts up JRuby stuff *much* faster than Hotspot). - Charlie - Charlie -- You received this message because you are subscribed to the Google Groups "JVM Languages" group.
