Subject Index.list in JAR files

Silly question.

When exactly does the classloader use this? i.e how much speedup does it
really give?

The sun docos say network classloaders, for applets and the like can exhibit
speedup, but it seems to me that unless classloader and server are talking
HTTP1.1 for byte-range downloads, applets arent going to be able to
selectively load files from a JAR.

Web start, on the other hand, should be able to use it. So, is that the
place where it is used? Does anyone have any quantitive data on the speedup?
