The first thing to note about the test is the impact of the pareto distribution and the start from an empty store, on what is actually being tested. At the start of the test there is a 0% chance of a GET request actually finding an object. Normally, it will be 3 hours into the test before a GET request will have a 50% chance of finding an object.

Both leveled and leveldb are optimised for finding non-presence through the use of bloom filters, so the comparison is not unduly influenced by this. However, the workload at the end of the test is both more realistic (in that objects are found), and harder if the previous throughput had been greater (in that more objects are found).
