Please Hugh, post the script or at least parts of it. I have been doing 
lots of database filling recently and might be able to give you a few 
pointers. Here's the general ones: 

Profiling is often no use, Benchmarking might just be enough. Roughly 
knowing where time goes to is a big help in guiding optimization. 

Be sure to try running it with a small data set, to speed up the test-
change-test cycle (or whatever the cycle is called in languages that you 
don't compile). Maybe even profile that way. 

Do you have a generation stage followed by a fill stage ? Or is the 
computation intermingled with database accesses ? 

hope to be of help
