re-index takes twoce as long on 2005..

Hi
I run a reindex of a 130GB dabase on SQL 2000 and it takes almost exactly 4
hours. IF I run exactly the same command on a 2005 box against a restore of
exactly the same database, it takes almost exactly 8 hours.
am I missing someting here? does a re-ind on 2005 work differently than on
2000? is it doing something twice that I havent asked it to, and that it must
be doing by default?
Any help would be appreciated.

Hi,
Can you see if you have enough room in LDF file while doing the reindex in
SQL 2005. Otherwise the autogrow will happen
and slow down the reindex command...
Thanks

slightly more thsan an hour quicker on my largest table...I think therefore

2005, specifically number of CPUs and IO bandwidth?
