Subject: [gentoo-user] KDE ridiculous memory usage

Hi list!

I have a bit of a problem. I'm on KDE-4.4.5 and it eats memory for
breakfast. Directly after booting, everything is okay but the usage
grows significantly. I wonder whether this is expected behavior.

The following statistics have been taken after 8 days of uptime during
which the system was on standby most of the time during work days and at
night.

free -m
             total  used  free  shared  buffers  cached
Mem:          3754  3588   165       0       57     258
-/+ buffers/cache:  3271   482
Swap:         6142   978  5163

A desktop machine that has 4GB RAM and still needs to swap?!

Okay, I'm used to Firefox taking much memory. I'm okay with that since
it's the most heavily used application currently running. But why does
Akregator need that much memory? It doesn't even have any tabs open at
the moment and is just running minimized in the background.

Virtuoso looks like an optional Soprano dependency which in turn is
needed for Nepomuk. Are the default use flags for dev-libs/soprano
suboptimal? What happens if I choose other flags for Soprano?

The rest of the list is a bit suspicious, as well. Especially DBus and
Kopete look like they live way beyond their means (or my means ;) ).

Do other users experience the same?

Thanks in advance!
