Simple explanation. Eclipse memory usage increased considerably in 2.1
(along about M4 time). It now runs at right around the default max memory
(100MB) which means when you experience the slowdown you are spending all
your time in garbage collection.
Try launching with -vmargs -Xmx256M and see if your problem doesn't go away.

Does anyone know what caused the increased memory usage or if anything is
being done about it?

I'll let someone else answer that, but the answer doesn't matter to you.
Even if it only increased a couple of meg, the problem is that on your
system you are using very close to the max memory, which makes Eclipse very
slow and unstable. So...

There is no actual Sun Java VM 1.4.1_01/_02 taken into consideration, which
most people nowadays use.
Beside this, a users/developers normal daily work would also involve many
editor related tasks, like opening different source files, inserting,
copying and pasting text, showing up help etc. I don't know if such issues
were somehow taken into consideration too in the shown measurements?
One thing I generally realize in allmost all Java IDE's is, if you do a lot
of text copy/paste and help popups etc. the memory consumption increases
dramatically fast and the overall performance slows rapidly down. Don't know
if it would be possible to automate such usual editing tasks for some hours
and try to measure them. - What I generally mean here is, that the users
common interaction with the UI parts, mostly produces much more memory usage
overhead than performing a (re)build and such easier automated/measured run
tasks. - Eclipse performs here somehow much better than other Java IDEs I've
used, but might also under special circimstances have possibly similar
problems. - There are situations, where the VMs occupy nearly max memory,
but aren't freeing it again in the same manner they allocated it, which may
be resulted to still referenced (not nulled) objects or dangling object
pointers and the like. This in turn always influences the way how and when a
garbage collection will be performed. The results are then slow harddisk
swappings. - However, AFAI can actually see, Eclipse behaves here much
better than other Java IDEs I've in use.

Who are you to tell me what matters to me? :-) Actually, I've used -Xmx256M
for quite a while now, so I haven't had any problems. I was only concerned
from the standpoint that I don't want to see Eclipse bloated unnecessarily
(assuming there is such a thing as necessary bloat).

It probably has something to do with my pattern of use (for one thing, I
