Hi,

[Oops, resent, made a mistake in trimming to the mailinglists as Petter

Agreed that lower memory usage is always a good thing. But Julian did a
great job reducing it already. And to put things a bit in perspective
classpath is not your average project. It has more then 4000 .java
files, totaling almost 1.000.000 lines, 150+ packages and the "simple"
class hierarchy tree page listing all classes relations and interfaces
(http://developer.classpath.org/doc/tree.html) is already 1MB. gjdoc
also generates cross references for all fields and methods it finds,
which are a really huge number for the "core" libraries. (Julian, maybe
gjdoc can print some statistics about packages, classes, methods and
fields indexed after a run.) All this doesn't mean I wouldn't be excited
if someone could look at the data-structures used and see if they can
trim some fat! :)

Also note that some runtimes use much more memory then others. For
generating the classpath documentation with gjdoc I really recommend the
natively compiled gcj version because that is by far the lightest on
resource usage (not to mention the fastest).

Cheers,

Mark
