Hello Everyone.
I have a problem regarding low transfer speed but it doesn’t look like it’s something that have already been posted. And since it’s my first FreeNAS install, I have found about it, of course, only after testing transfer speeds using SMB share. But when I dug deeper more peculiar things have appeared:
(MBP - MacBook Pro I used for testing with Thunderbolt to 1GbE adapter (I don’t know what chip is this but it’s supposed to be great; besides I don’t think it matters)
SV - server I am using as a FreeNAS platform with 2x Intel 82574L GbE NICs)
MBP: iperf -s
SV: iperf -c 192.168.1.3 -i 1 -w 128KB
Speed: ~940Mb/s
SV: iperf -s
MBP: iperf -c 192.168.1.1 -i 1 -w 128KB
Speed: ~600Mb/s
That was on FreeNAS 11.1 U5. On FreeNAS 11.2 Beta2 I was getting same results. In both occasions FreeNAS was installed on SSD. I have also installed FreeBSD 11.2 and results were almost the same as in FreeNAS: SV(-c)->MBP(-s): ~640Mb/s, SV(-s)<-MBP(-c): ~940Mb/s.
Because I have already checked the cable in other tests and confirmed it is ok and capable of saturating 1GbE both ways I didn’t know where to turn to… so I turned to CentOS. Between MBP and CentOS 7.3 on SV I was getting constant ~940MB/s for SV as a client and ~840MB/s when SV was acting as iPerf 2.0.12 server. Still not getting 1GbE but much better than while using FreeNAS/FreeBSD. So I went and confirmed this by transferring file using SCP and results were the same: ~110MB/s down and ~100MB/s up.
So I fired up FreeNAS 11.1 U5 again and tested file transfer with SCP. ~30MB/s down, ~20MB/s up.
Also, cyberjock wrote in one of his posts that he uses/used same NICs and they should work OOTB…
I am stumped now. What’s going on? Those are the same machines, disks, NICs, cable, etc. Why there is such big discrepancy?
Maybe someone has seen something like that and would like to shed some light on what might be the culprit here. Possibly it might not be a problem in respect only to FreeNAS but it is more apparent there.
I am a noob when it comes to networking so any help would be appreciated.
SV:
Supermicro X8DTE-F
2x Intel E5620
48GB ECC Registered
2x Intel 82574L GbE onboard
2x Samsung 830 SSD plugged directly into motherboard (Intel ICH10R SATA 3.0Gbps Controller)
I have also Adaptec 8505 RAID card with 6 disks attached to it but let’s say I won’t be using it for now… I don’t want to make PROs angry when I need them the most ;)
Final note: SV is headless and I’m using IPMIView from Supermicro as a not very comfortable KVM and I don’t think it’s possible to copy an output, but using SSH I can provide any type of results that might help.
FInal final note: I am trying to set up FreeNAS as a main NAS at home and I did some tests regarding different volumes’ types but no matter what type I chose I couldn’t get past that ~60MB/s (stripe, mirror, RAIDZ1; SSD, HDD) so I think resolving problem described above is paramount.

- initial test (MBP->SV via SMB) show slower than possible transfer speeds: ~60MB/s. I thought it was odd since I have created stripe volume on SSD directly plugged to motherboard.
- then I confirmed this behavior by testing AFP share with the same connection between MPB and SV
- about that time I started to check everything I could. I used iPerf 3 to check cables, switch, router and my other computers. I was constantly getting ~940Mb/s (~110MB/s) between my other machines in both ways
- I returned to testing connection between MBP and SV by using installed on FreeNAS iPerf 2. My results were strange, at least for me:
MBP: iperf -s
SV: iperf -c 192.168.1.3 -i 1 -w 128KB
Speed: ~940Mb/s
SV: iperf -s
MBP: iperf -c 192.168.1.1 -i 1 -w 128KB
