What is the signifigance of a fillfactor of 20?
@ 20 % you're consuming 5 times the disk actually needed for the index. I'm sure there's some business case where that might make sense, but I've never seen it. If you aren't rebuilding these regularly (rebuild returns to original fill factor level, in this case 20%), I'd be interested to see how full the indexes are after a month of operation.
