Is compiz on? (desktop effects in the 'appearance' options) If so, try
turning it off. If you have a crappy videocard you'll be loading a lot
of textures into main memory, possibly causing that 1 gig to fill up

You could also try installing iotop and running that. Usually if a
system seems slow, it's because of trashing on the disk. This could be
by running out of memory (going into swap) or having some very IO
intensive process running.

akonadi (if it is like the other indexing systems) doesn't just index
file names, it indexes content as well. A bit heavy on the machine but
most people use files all the time and it can be handy to just type in
'chocolate chip cookie recipe' and get your recipe and some bookmarks
you made on a cooking site.

I don't use it anymore atm (ran beagle and tracker for a while, but
they had some problems), but I kinda get the idea. When it works,
