My expectation is that the only thing the padding numbers would effect with 
regards to execution time would be cache hits and misses.  If there is 
something subtle going on though, then those sizes need some comments and 
rationale.  "93481" looks like it was pulled out of a hat, and it is large 
enough on it's own to overflow many embedded stacks.
