It wont make any difference if the memory mapping settings are just larger than the file sizes, or a lot larger.... therefore fiddling with those settings wont make any difference from your original test.
Generally when people see very high performance it is because a lot of the data they are traversing over is already in memory, i.e. the caches are warmed. So is this test you are running just from a cold start, and if so can you try the test twice, within the same vm that is.
