While we have tested a number of Linux distributions on Intel's new
Xeon Scalable platform, here are some initial BSD tests using two Xeon
Gold 6138 processors with the Tyan GT24E-B7106 1U barebones server.

Of course. Yet many users here might like to compare common things:

o iozone if disks are not limiting factor

HyperThreading on Intel Xeon Haswell, a benefit?
What bits of FreeBSD are aware and can take proper advantage of
Intel HTT, such as its thread/process schedulers (sched-BSD/ULE/...),
etc?
What system/app loads are, or are not, likely to benefit with today's
HyperThreading CPU's? Kernel (ZFS/crypt

I didn't actually solve it or do anything.
I just upgraded to RELENG_8.
Now it's behaving more like FreeBSD should.
I can do sequential reads/writes and still
use kbd/mouse/X11/buildworld and so on.

No, but for geli hifn(4) crypto(4)/(9), geli(8) might work
if aes-cbc is indeed the mode geli uses. See the source I guess.

Yes. There are trays and cable dongles and things that do aes/des.

Well, you can set {id,rt}prio and nice on kernel processes. Then
look at top to see the nice column change. Have no idea what effect
it has nor what the non '-' chars on those procs in that column
mean.

Well, I've got a gig free in /usr/local which is ufs2+softdeps. So
I just dd if=dev/zero bs=1m of=zero there. Disk was 100% busy, cpu
was 10-15% system, 10% user, about 16MiB/sec.
Of course since that is my system spindle, and it was busied out

Hi. I'm running RELENG_7 on an older single P4. It has a lot of
disk on it that does mainly sequential read/write of gigs of data.
The data disks are hanging off a dumb ata133 pdc20269 card, they
use geli aes 128 and zfs sha256, single spindles. Free ram, no swap,
free disk, no net, etc.
