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.
