KDE 4.10 slow

Upgraded to KDE 4.10 (32-bit) yesterday and I wish I hadn’t as everything is running ohhhhhhh, soooooooo, sloooooooow. Anyone else noticed this?

My machine loads bit slower then before the upgrade to KDE 4.10, especially after login. When you start a computer you usually do it for a purpose and immediately after login you click some apps. An they load slower too… Ksysguard shows that Virtuoso and Nepomuk are hitting the ceiling with CPU usage at the beginning. First I have all 4 cores 95% busy, later they calm down a bit, but still take 25% of the total CPU resource. After a few minutes they eventually switch off.
