Long processing time on pyramid creation on a raster dataset

I have a 24 GB raster dataset on my sde that I wish to have pyramids build.  When I created the raster file initially via arctool box, I made sure none of the pyramids or statistic are built by unchecking the boxes under raster storage environment.  I double checked using sderaster command line to ensure no pyramids were created.  Initially, when I ran the pyramid building process via arctool box, it ran for 2 weeks and never finished.  I killed the process even though arccatalog told me there were pyramids.  However, I cannot view it unless I zoomed way in.  I removed the pyramids via sderaster command and decided to use the sderaster command to rebuild.  Now, it has been running for 24 hours, and still not yet finish.  However, when I use the sderaster command line to describe the raster, it tells me the pyramids are there.  Should I stop the process?  The last time I ran this on a different sde, it took less than 1 hour.  Why is it taking longer?  Could it be the set up of the database causing the issue?  I am running on 9.3.1 on all platform.

Hi Jake,

Good point.  I will check with the server admin and hopefully we can make the upgrade (not sure when).  I will repost if after the upgrade things still don't work.  Thank you for all your help.
