Why do you run two different tests? Accessing two different files, and 
running the tests with different options sounds like a bad idea if you 
want ot compare the results.

I'd re-run with the same options for both versions, probably the tests 
should be ran several times. I would also be interesting to know what 
happens on the server during the tests. Memory pressure, CPU load, 
context switches, that kind of things.
