In my recent experience finding a distro that wouldn't lock up on my machine, I had the problem of akonadi slowing my machine so much it acts almost as if it's locked up.   Even on slackware 14 it was a problem.  A minute or two after starting kde, the system stopped doing whatever it was doing.  I would press ctrl+esc to bring up the system activity window and I would literally have to wait a minute or two before it appeared.  Every time there were 4 or 5 processes with akonadi in the name that together consumed 8GB of memory.  Once I closed them the system returned to normal.  A few days ago I figured out how to disable them.  I've had no problems since.

It used to be true that it could eat your system alive, these days it's mostly transparent, and when 4.10 is released next month it contains a major rewrite of the whole system and should be even more transparent.

If you leave it enabled, it can do a lot of really neat things like let you search for files based on their contents and tag files with all sorta if information.  For instance you can tag your pictures with information that would allow you to quickly find pictures of people, places and things from all over your hard drive.  In fact if you use Digikam, it has the ability of automatically tag new images of people based on facial recognition of people you have previously tagged.
The KDE programs automatically add all sorts of info, so you could even find files based on where they came from, so when you save attachments in kmail they are tagged with where they came from, so you could search for libreoffice files that came from person@place.com with the words "dog" in the document.  All pretty cool.
It does a lot more, but those are some of the highlights.  I used to turn it off because it had a tendency to eat enough system resources to become noticeable, but that was a couple of years ago.  These days I just leave it turned on, and I never notice it indexing anymore.

Does anybody use Akonadi, Nepomuk, Strigi, Soprano, Virtuoso ?

What is the purpose and benefit of all this stuff?

Doing "locate akonadi" on my system found more than 200 files.

Is there any good reason not to get rid of any and/or all of this stuff?

I have read that they just eat up space and memory and cause one's system
to run slower.

Where can I find a list of other changes I could make to make my systems
less cluttered and more efficient?
