FreeNAS and Slow Network Speed

[Stephen Wales]

I am running 9.2.1.2 on a Gigabyte AMD E-350D, I have set it up only as a standalone owncloud server and I am trying to do an initial backup from a workstation on the same internal network. This workstation was regularly backing up to another owncloud server with a standard owncloud install prior to this and getting 79-90MB/s now its only achieving about 80-90KB/s to the E350.

Is there a know issue with this motherboard or is it something I need to change with the FreeNAS owncloud Plug-In that I didn't need to do with a normal owncloud install

Which NIC driver is being used (from ifconfig)?

ifconfig re0

There's your culprit. Ditch the realtek and replace it with an Intel.

It's a realtek chip on the board will this not cause a problem, how do I change it ti Intel?
I do get decent LAN speed when going into the webgui etc, plus I get decent throughput to the Time Machine afp share

You can't change to the driver to an Intel, without adding an Intel NIC. While it could indeed be part of the problem, I *think* there are other issues at play.

You originally said "This workstation was regularly backing up to another owncloud server with a standard owncloud install prior to this and getting 79-90MB/s now its only achieving about 80-90KB/s to the E350."

What were the spec's on the other owncloud server? The E350 has a 1.6GHz CPU.

Is the machine you're backing up connected wirelessly to the network?

Lastly, unless you have a use case for the cache drive, it could cause performance issues.

Are those Barracuda low power or "green" drives that have the auto-spin-down "feature"? If they're going to sleep at an inopportune time that will destroy your throughput.

Also as gpsguy states, you likely don't have a proper use case for that L2ARC drive.

Stephen,

Try this.. Open the settings for your main network interface, and just hit the ok key. See if your throughput changes.

The nd6 options on all the epair interfaces for the jails change from "nd6 options=1<PERFORMNUD>" to "nd6 options=9<PERFORMNUD,IFDISABLED>"

(Also the bridge interface)

In my case my speed increases over 300%..

Upon reboot all of the epair interfaces and bridge interface revert to "nd6 options=1<PERFORMNUD>"

I think whats happening here is that the IPv6 is not in use on a jail which is installed but IPv6 is still up, and causing some issues... all the other interfaces like physical nics, etc are setting IPv6 as IFDISABLED correctly if IPv6 is not configured.

(Thanks HoneyBadger for pointing me in the right direction to identify the difference.. ifconfig -a before and after sussed it out.)

I'm still digging into this to be sure.. but it SEEMS to be what is happening on the surface to me, in my case. Not sure how to fix it on boot, because adding what you see below doesn't help, even though that seems to be the right commands... there has to be something else happening.
