It may be problem you're running into with your 401K document is that
Eclipse itself, not just the editors that run in it, is something of a
memory hog. If you're running Eclipse in its default max memory, around
100MB, any significant work you do will get Eclipse near the limit,
putting you into a constant garbage-collection mode, which slows things
down considerably.
I personally don't run Eclipse except with the following added to the
command line:
-vmargs -Xmx256m
I know this comes as a shock to people coming from emacs or otherwise
unused to running in an all-Java environment not particularly tuned for
low memory usage, but there it is. The question is, do you want to spend
your time optimizing away the need for a <$100 memory chip?
Everyone's idea of 'ready for prime time' will vary, but I assure you
that people edit 400K XML documents all the time with XMLBuddy without
ill effects. (The memory usage for relatively small documents like this,
BTW, depends as much on the complexity and nature of the DTD or schema
behind the document.)
