We're connecting to a database, but it includes only a few (about 20) 
subscribers, nothing else.  We didn't stress test the database 
(-connection). Without memdebug kamailio runs fast.

Most of the time the CPU seems to be idle. Sometimes syslog shows up in 
top, but without much CPU time.
Do you think this could be a dual-CPU issue? Perhaps syncing the memory 
access between the CPUs is slow?
If you like to see the complete logfile we can post this too.
