Bug 293347

Version:           unspecified (using KDE 4.7.2) 
OS:                Linux

I was on openSUSE 11.4 and now upgraded to 12.1 (kde 4.7.2), and I can't work anymore as simply everything is extremely slow. kontact/kmail eats cpu+ram together with all that stuff that it suddenly needs (nepomuk,akonadi,virtuoso). This is a 6-core cpu with 8GB RAM, and it's so slow even Windows would run much faster. What can I do to get a working system again?

Reproducible: Always

Steps to Reproduce:
Start KDE with kmail and firefox - try to work. All was good in kde 4.4. I've also had a very hard time upgrading kmail, but there have been thousands of complaints to that so I guess you know it already ;-)


Expected Results:  
A quick and working system - at least quicker than Windows, please!
