High cpu usage and extremely slow

Hi
I'm running alfresco community 4.2.e on a machine running Red Hat Enterprise Linux Server release 6.4.
It's a default alfresco setup apart from openjdk 1.7 instead of the one in the installer.
I am reading and writing documents form/to alfresco using apache chemistry OpenCMIS.
Everything seems to be working fine until I upload a document, because after that every attempt to retrieve a document takes >20 secs. Every read seems to get stuck on the db-call because a new postgresql process is started and eats lots of CPU and takes forever to finish.

Moreover have I also encountered the java-process running tomcat to for no obvious reason start using 150-200% cpu for hours straight (until I finally restart the service).

I have about 10 to 50 documents (images + thumbnail renditions) in my repo.

Any ideas?

/Viktor
