Matt,
Meaning?=C2=A0 How does -O0 optimization and INVARIANTS affect this?=C2=A0=
=20
Personally, I find everything on Phoronix "out-of-the-box" FreeBSD and opti=
mized Linux.=C2=A0 *shrug*=C2=A0 Apples? Meet Oranges.=C2=A0 I make my mone=
y as a contractor supporting RH/CentOS, but it's always funny to give peopl=
e the heads up on who uses FreeBSD as their starting point and to let them =
know the home network runs on FreeBSD.
When people think Linux (which they believe is the only OSS "Operating Syst=
em" out there)=C2=A0 I have to explain kernel and user space and then expla=
in FreeBSD is both and then show them the numerous CVE exploits for that ye=
ar.... 150+ versus ~15.=C2=A0 Faster is not always better, especially when =
you're circumventing standards to get that speed. (I remember the IIS vs Ap=
ache wars....=C2=A0 Turned out that IIS was not doing things properly and c=
ircumvented a lot of exploit protections for that speed.)=C2=A0=20
Building an OS that does everything well OOB, FreeBSD can do that.=C2=A0 Op=
timize for application specific....=C2=A0 It usually wins, places or shows.=
=C2=A0=20
Sadly, I didn't realize that FreeNAS was using OpenZFS vs the FreeBSD ZFS.=
=C2=A0 Here's my question.... Why?=C2=A0 It was my understanding that SUN m=
ade it OSS and there are conflicts with the CDDL and GPL.=C2=A0 It seems si=
lly to lose performance for no reason.
As for phoronix, I read it for a laugh.=C2=A0 It's funny how so many "Linux=
is everything/rules" people I meet who just use it as a shield and have ne=
ver evaluated the kernels of both and the surrounding userland.=C2=A0 The F=
reeBSD project is tight, goes through a proper QA and release cycle and out=
pops, even a x.0 release, a fully useful new OS version with everything ne=
at, tidy, functional and fast.=C2=A0 (So, if FreeBSD can do this, why are a=
ll the crazies that are producing software screaming AGILE and quick releas=
es which still has not solved the problem of crap code?)
Ooops, bit of a rant.... sorry all,
Paul

These were run with ZoF compiled with -O0 and INVARIANTS. Take what you
read with a grain of salt.
