Poor LAN Performance

[benji0001]

I have an issue where my LAN is extremely slow. If I conect to my NAS via SAMBA and try to copy files over it is done at a rate of only 22MB per second. This is really slow considering I have a 1GB NIC in the NAS and computer that I am transfer files from. Is there a way to increase this throughput. I am also running RAID via ZFS on a plus 10GB storage system. Any ideas would be appreciated

We'll need a lot more information about your systems and your network to have any chance of helping you.

Sorry for not adding more specifics;
PC-Q18 Mini-ITX Case
ASROCK Z87E-ITX Motherboard
Intel(R) Core(TM) i5-4670K CPU @ 3.40GHz
5-3TB Western Digital Red Drives
16GB Memory
FreeNAS-9.3-STABLE-201602031011
Plexmediaserver 0.9.15.6.1714
Crashplan 3.6.3_1
Windows (CIFS)

If there is a way to export the reports from Plex I will try to do that, but I haven't figured that out.
If there is anything else you need to know let me know and I will try to get it for you.

Thanks

Why would we need any Plex reports? This is a FreeNAS forum.

I'm guessing your motherboard uses realtek NIC?

I'm guessing your motherboard uses realtek NIC?

According to ASRock, it has a 'Giga PHY Intel I217V' chip: http://www.asrock.com/mb/Intel/Z87E-ITX/?cat=Specifications

That chip seems to be supported by FreeBSD/FreeNAS. But this mobo is a prosumer/desktop board without ECC RAM and therefore not the best choice for FreeNAS.

Also, post the output of ifconfig.

 

[jgreco]

And tell us how full your pool is ("zpool list"), also the output from "zpool status" would be helpful.

 

[Robert Trevellyan]

and your network

Including routers/switches/layout ...

RAID via ZFS on a plus 10GB storage system

Probably not. What @jgreco said ...

At almost 70% full and 16% fragmentation, you may be seeing natural degradation due to fragmentation. What are your write speeds like if you try writing to the pool directly on the NAS?

 

[benji0001]

for my network setup its as follows:

cable network router
four computers (laptop, 2-desktop, freebsd media server)
any wifi that connects (phones, tablets)

 

[benji0001]

my speeds have have always been this slow even when I first started using it

 

[anodos]

You can use iperf to get a baseline for your network performance.

Make sure your clients and server are negotiating smb2/smb3 connections.

 

[benji0001]

sorry can you tell me what the command is? i'm not sure which command to add to iperf to get the base line

 

[SweetAndLow]

On freenas you run 'iperf -s' then depending on your client os you will need to run the client version of iperf. You should also run it the other way around by making freenas the client.

 

[benji0001]

ok I tried to run iperf on the freenas machine as the server and my desktop as the client with no luck. I also tried switching the roles where the desktop was the server and the freenas was the client. each time the machine would connect by not transmit anything. I was able to run iperf between the desktop and itself and it worked fine with the following results:
iperf3 -c 192.168.1.13

iperf Done.

I tried pinging the freenas machine from the local desktop and it worked fine. I tried pinging the local desktop from the freenas machine and it timed out every time I ran it. I'm not sure why its working in one direction only.

 

[SweetAndLow]

Does freenas have its network configured? If using static ip you need to set the gateway and nameserver.

 

[Robert Trevellyan]

I'm not sure why its working in one direction only.

Firewall?

 

[cyberjock]

Those iperf tests confirm there is a networking problem. You should have gotten at least 850Mb/sec.

 

[benji0001]

I'm beginning to think this is a firewall issue within my desktop windows 10 machine. I managed to finally turn off both installed security device and windows firewall. I then tried to ping from the FreeNAS machine to the desktop and was successful. now when I tried to run iperf again between the two machines I still couldn't get a throughput test running. I can run as client or server on the FreeNAS without issue but can't get any data passing. I shouldn't have to put I'm tempted to put in some static routes and see what happens.
