What kind of data was scanned?
Was it hand-crafted, automatically generated, or real world files?
What is the confidence of the values you measured?
(I don't see if you've repeated the experiment or not, there is no

the DB.

Results from benchmarks with such a low signature count will be useless
in practice.

Hint: larger tries don't fit in L2, and also produce a lot of DTLB misses
