It works out to some crazy number:

And my results:

Of course this is too good to be true:) which means it is! You have compression enable for your volume. Zeros are highly compressible.;) Turn off compression for the volume when benchmarking. I checked and this isn't mentioned in post #1 or anywhere on the first page.

For my true results see [post=26680]above[/post].

PaleoN,

Good catch, it's true, that isn't mentioned but it definitely makes a difference / causes inaccurate results.

Hello everyone,

Thank you for the compression heads up.

Now the numbers are more realistic. However, I am still very happy with it.

Shaite? :-|

Onboard Realtek NIC
Raidz2 with 6x Seagate 7200.9 500GB (ACHI)

Shouldn't i be seeing better write performance than this?

Found this thread when looking for solutions to my slow Read/Write issues so may as well post my results.

HP Microserver N40L
2x4GB Kingston non-ecc RAM
6x Samsung F3 1TB running ZFS1

Code:
[louis@freenas /mnt]$ dd if=/dev/zero of=/mnt/RAIDZFS1/tmp.dat bs=2048k count=50k
51200+0 records in
51200+0 records out
107374182400 bytes transferred in 486.570614 secs (220675436 bytes/sec)



Code:
[louis@freenas /mnt]$ dd if=/mnt/RAIDZFS1/tmp.dat of=/dev/null bs=2048k count=50k
51200+0 records in
51200+0 records out
107374182400 bytes transferred in 271.686132 secs (395214072 bytes/sec)
[louis@freenas /mnt]$


So it certainly doesn't look like my drives are to blame in any of this which is good news.

and i look for CPU Intel Pentium G2120 - its faster, has lower TDP and supports PC3-12800 (as my RAM), against of G630 (only supports PC3-8500)

ps sorry for my english

Hi, just ran these test, and I got 244MB/s write and 302MB/s read with the following hardware:


SuperMicro X9SRL-F motherboard
Intel(R) Xeon(R) CPU E5-2603 0 @ 1.80GHz
8GB of memory
16xSamsung Spinpoint 204UI harddrives spread across 2xRaidZ2 vdevs
IBM M1015 HBAs flashed with LSI firmware

Should I be happy with these results?

The results don't matter as long as you are happy with your system performance. For the number of hard drives you have(you didn't mention their size) buying more RAM will almost certainly increase performance. The manual recommends your RAM follow the 6GB + 1GB for each TB of hard disk space. I'm pretty sure you are far far below that.

Thank you. The 204UI drives are 2TB drives but you're right that I could've added that part as well.

It's just a mediaserver Connected with a Gbit so I can't utilize anything above 1Gbit/s (2Gbit/s when I start using the 2nd NIC) but it's just nice to know where the bottleneck is, I do have 32GB of memory on the shelf that was supposed to put in a TV-server but it didn't work with the motherboard so I Guess I can put them in there as well and see what happends.

Thank you once again.


edit:

Another question, I'm thinking of using 3TB drives for further expansion that won't effect the performance in a negative way as long as I keep 3TB drives and 2TB drives in sepereate Vdevs will it?

rz2 ws rz1 differences (see my test above, 6 disks at rz1 is faster)?

Fractal Node 304
SeaSonic SSR-450RM (modular, 80plus Gold)
ASRock FM2A85X-ITX (7 internal SATA3 ports)
AMD A4-4000 (65W TDP)

6x2TB WD Red
ZFS raidz2 (mostly empty)
booting from internal USB stick (had to keep USB 3.0 disabled due to crashes)

All testing using 100GB transfers via "dd if=/dev/zero of=... bs=2048k count=50k” and "dd if=... of=/dev/zero bs=2048k count=50k”, with compression disabled.

Most testing performed with rudimentary sysctl tuning:
Code:
net.inet.tcp.sendbuf_max    16777216
net.inet.tcp.recvbuf_max     16777216
kern.ipc.maxsockbuf           16777216

net.inet.tcp.sendbuf_inc     16384
net.inet.tcp.recvbuf_inc     524288
net.inet.tcp.inflight.enable 0


Later testing performed with powerd enabled, and more sysctl/tunable tuning after some research:
Code:
tunables:
kern.hz  250        Reduce kernel interrupt frequency for power savings
 
sysctl:
net.inet.tcp.recvbuf_max    2097152    Recommended for up to Gigabit Ethernet speeds.
net.inet.tcp.sendbuf_max    2097152    Recommended for up to Gigabit Ethernet speeds.
kern.ipc.maxsockbuf         2097152    Recommended for up to Gigabit Ethernet speeds.
net.inet.tcp.sendbuf_auto   1
net.inet.tcp.recvbuf_auto   1
net.inet.tcp.sendbuf_inc    65536      1/4 of what’s suggested for Gigabit Ethernet (doing WiFi here)
net.inet.tcp.recvbuf_inc    65536      1/4 of what’s suggested for Gigabit Ethernet (doing WiFi here)
net.inet.IP.forwarding      1
net.inet.IP.fastforwarding  1
net.inet.tcp.mssdflt        1460        MTU size
net.inet.tcp.rfc1323        1          Allow send/recvspace to exceed 64KB
net.inet.tcp.sendspace      411720      Congestion window: 80Mbps * 40ms
net.inet.tcp.recvspace      411720      Congestion window: 80Mbps * 40ms
net.inet.tcp.slowstart_flightsize 141    (sendspace / MTU) / 2 - Bet that the connection is good, ramp up quickly.
net.inet.tcp.delayed_ack    1
net.inet.tcp.delacktime     100        Piggyback ack’s onto the return packet in most cases.
net.inet.tcp.inflight.min   6144        Suggested by tuning(7)
net.inet.tcp.inflight.debug 0
net.inet.tcp.inflight.enable 1          Dynamically limit throughput to optimize buffer usage on variable speed connections (WiFi).
net.inet.tcp.hostcache.expire 3900      Don’t expire the cache right when a host does its hourly checkin.

So, regrettably, the maximum throughput in my case has very little to do with reality. I want full disk encryption, and I’ll primarily be using the NAS via WiFi (our household is nearly free of cluttery cables).

Performance is seriously impacted by all factors shown above: underpowered CPU for encryption and compression (though hardware encryption was found and used), slow Gigabit ethernet, even slower 802.11n WiFi (with a very open 5GHz spectrum and while sitting in the same room as the base station)...

But ultimately, I’m getting what I wanted: a storage solution that’s hardened against bit rot, and reasonably fast, large, and WiFi-accessible.


By the way, power consumption is reported by my Kill-a-Watt as follows:
Code:
without powerd:
~40-42 watts idle, drives spun down
~53-55 watts idle, no drive spin down
~61-67 watts under full load (no encryption, no compression)
 
with powerd:
~35 watts idle, drives spun down, powerd enabled
~50 watts idle, no drive spin down
~59-69 watts under full load (no encryption, no compression)
~59-71 watts under full load (with encryption, no compression)
~55-74 watts under full load (with encryption, compression)

You know, my FreeNAS server with no drives.. Xeon e3-1230v2, 32GB of ECC RAM, dual GB Intel LAN, uses less power than your machine at the wall. Mine sat at a solid 35watts with powerd off. Plus, since I have AES-NI I do use encryption for one of my zpools. :p
