Not sure. But in case you'll get much more similar (CentOS vs. FreeBSD)
results from "simple" OLTP test, as opposed to very differrent numbers
for  "complex", it's probable that the cause can be somewhere in jemalloc,
as we've observed in our tests. And at this point, we can rule out
anything else (ZFS, scheduler, etc.) and knowledgeable people can focus
on one specific piece of code.
