Sorry. Just after sending my post, I've realized that version is missing. I have the same version as Nuno, 8.1.7 (.0.0) on NT4. I've tried to reproduce my numbers, but failed. My test box is too small and I have not enough time. So maximum number of extents I've got while inserting 2.000.000 (80 MBs) rows in table in tablespace with uniform extent size 8kb.

Note: pagesflames_at_usa.net has been cancelled due to changes (maybe we
can call it an overture to bankruptcy) on that server. I'm still using
this email to prevent SPAM. Maybe one day I will change it and have a
proper mail even for news, but right now I can be reached by this
email.
