10Gbe Tuning?

What fiber sfp+ modules are you guys using for the intel x520?
I use mostly Direct Attach cables, not optics, but when I do use fiber it's either genuine Intel modules or knockoffs from approvedoptics.com.
Nice, regular 8431 cables like http://www.ebay.com/itm/Intel-XDACBL5M-Twinaxial-Netwrk-Cable-Twinaxial-Netwrk-16-40ft-SFF-8431-Male-/311114486894?pt=LH_DefaultDomain_0&hash=item486fde546e or? And this card is 2x10gbit full duplex? if so, possible lacp @ 2x10gbit?

Yes, cables like that.
Theoretically, yes, you could put two links together for 2x10Gbit/s.

Now do the math on 40Gbps NICs and a $99 break-out cable. :-)

on my actual setup - J1900 + ssd + 8gb ram and 2xIntel i210T
For PPPoE i got verry low speed. Around 346.96 Mbit/s. connection is 1000 Mbit/s.I'm not expecting to get 1000 but @least 50%
dev.igb.0.%desc: Intel(R) PRO/1000 Network Connection version - 2.4.0 -
What CPU usage are you seeing?

How does that divide across the cores? I imagine you have one core at 100%
Steve
-
one core is reaching 100% yeah…rest of them are low in load.

Are you able to adjust this over the PowerD function perhaps?
-
According to what I have found on the forum this is meant to be "adaptive"
Found that we can change the parameters by editing /etc/inc/system.Inc
Or în gui via system - advanced - miscellaneous. -

Yes this I was meaning, by an Alix APU we where seeing the throughout gaining
from ~450 MBit/s to 650 - 750 MBit/s only by activating or changing the PowerD options. -
Sounds pretty nice !

Nikkon, this fits your use case: https://redmine.pfsense.org/issues/4821

Thx Steve ;)

It explains the low throughput in one direction but there's no solution to it as yet. Havne't tried the suggested patch but we are at least aware of it now.

Waiting for it ;)
Thx for the update. -
as an update on all my systems with igb i got
sysctl -a | grep '.igb..*x_pack'
dev.igb.0.queue0.tx_packets: 38931223
dev.igb.0.queue0.rx_packets: 42548203
dev.igb.1.queue0.tx_packets: 39439021
dev.igb.1.queue0.rx_packets: 36697705 -
I found another thread pointed to this circumstance where this would be really nice explained.
mbufs tunable
Also have a dedicated view on the named pfSense versions please. -
Nikkon, you only have one queue per NIC in each direction? You have a 4 core CPU I expect to see at least 2 queues. Do you have a tunable set to limit that?

Is there a recommanded value?
