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. -- Daniel Bilik neosystem.cz
