Strange to say, I have indeed heard of a JIT (Just In Time).
But to the best of my knowledge Java doesn't cache the output of Hotspot on
the local drive in a native format - last time I looked all I could find
were .class files, not .exe's!
Thus every time you run your Java application that old Hotspot machine has
to redo all the hard work of translating to the .class file to a native
machine instruction set. This takes time... As I understand the .Net
architecture, after you have done your first run floating around somewhere
in a cache on your hard drive will be an executable image in native machine
instructions. From that point on this native image will be used in
preference to the MSIL image. However, if the MSIL image changes then the
native image will be regenerated. Its the old trade of storage vs. space.
If I have this wrong then I am in no doubt that you will correct me (and
believe me, I do appreciate the learning).
