Today I accidentaly found out who is eating all the memory on my system and makes it slow after a few days: Xfdesktop.

Since I couldn’t start any programs via menu on the desktop, I killed xfdesktop and started it again. After that only ~100MB of my Swap were in use whereas it have been ~1000MB before. And my system works faster now. Up until now I suspected Xfwm4 for being the performance eater.

Please ask if you need more info.

Reproducible: Always

Steps to Reproduce:
1. Start xfdesktop
2. Run system for a week or so
3. Watch output of top
4. Kill xfdesktop & start it again
5. Watch output of top again
Actual Results:  
A considerable amount of swap was freed after restarting xfdesktop.
