The interesting bit is that integers outperform packed decimals on adds *by a factor of 20*. Yeah, you read that correctly. Integers are 20 time faster than packed decimals on adds.

Only by a factor of 20? That *is* a surprise. I would have expected at least a factor of 50.

That would depend on your machine architecture. If you have packed decimal opcodes at the machine level, you can get some really good performance.
