No, what I meant whas that creating an index on a table with data after 
the data has been COPYed, is faster than having one large table with an 
existing index where data is added all the time and the index is 
updatesd along with that.

I did do a performance test some time ago on that or something similar, 
I dont remember the exact details, but what ever I tested it was slower. 
But I will try exactly what you suggested tomorrow, when at the test 
machine. The issue is it has to runn for some time before it is possible 
to see any lasting degradation in performance.
