Understood Ron. The point that Tanel and I are trying to make is, if the
process is slow, there is a bottleneck somewhere. You can use Oracle features
and O/S tools to determine where it is. Once you've done that, you're one step
closer to solving the problem. Until you understand the behavior, you're
nowhere.

There are several exports in different databases, exporting various size
objects. The thing is, this started about the middle of December.
Before that, everything was fine.

And when you should see from v$session_event and v$session_wait that
database itself is not the bottleneck, you could run truss -c on the exp
process for a while and see the breakdown whether any system calls (like
write()) take lots of time.
Are you exporting lots of small objects or few large objects?

What does V$SESSION_WAIT tell you about the session executing
the export?
