I mean that I might be chasing noise and the mean+stddev for throughput in
version 16 pre-beta so far appears to be similar to 15.2. When I ran the
insert benchmark a few times, I focused on the cases where 16 pre-beta was
worse than 15.2 while ignoring the cases where it was better. Big
regressions are easy to document, small ones not so much.

Regardless, I am repeating tests from both the insert benchmark and
sysbench for version 16 (pre-beta, and soon beta1).
