To find our reasons I would try to find out if it's I/O-relatet or what's
the reason for it.

If you have such situation try 

# x_cons <DBNAME> show active 1

This will show you the active threads and their states (I/O wait, Vwait
etc.). Then you could eventually see, if there are locks hold,
I/O-bottlenecks etc.

The other tool is the dbanalyzer. It will give you some hints where to look
at and what to change.
