It looks like you have very high water marks and/or high fragmented segments

Subject: export with "first rows"

Hello,
    We have the optimizer mode set to "first rows"
on our (25gb) database to meet a vendor requirement.
When I do an "direct" export, it runs for 6-7 hours.
 
When I change the optimizer mode to "choose" it
runs in around an hour.
It also runs in an hour when I set the the optimizer
mode to "first rows", and run stats on the "sys" schema.
 
I'm curious why this occurs. Has anyone experienced
this ? Any ideas why this happens ? Is this normal behavior ?
I could not find anything on metalink. thanks.
 
Oracle 8.1.7.2, aix 4.3.3.
