Load updated Intel IX module to get 10Gbps

stephenw10

Yes that should work. You should also be able to do both at the same time.

I would want to be sure I had some out of band access whilst making that change. That could be via the console or assigning an interface for management access.

ogghi

@stephenw10 That's kind of what I tried, but it wouldn't work, as I mentioned above it would not apply fw rules, NAT etc.
So I restored from backup...
When doing such things I always have a monitor + keyboard ready in the rack for local console access ;)

@stephenw10
I managed to change interfaces.
Still no improvement, I even tried to remove some advanced settings:

I guess time to test some tuning, but given that we will need to restart each time, I need to do it early morning or during next maintenance window...

Any suggestions?
I still have some things in /boot/loader.conf.local

net.inet.tcp.tso="0"
if_ix_updated_load="YES"
hw.ix.flow_control="0"
hw.ix.num_queues=40
hw.ix.enable_aim=1
hw.ix.max_interrupt_rate=30000
kern.ipc.nmbclusters="1000000"
kern.ipc.nmbjumbop="524288"
machdep.hyperthreading_intr_allowed=1

Might make sense to remove, reboot and try?

Ok so you're using the Mellanox (mce) NICs now? And still seeing ~4Gbps? Per core CPU usage is still low when testing?

This seems even worse right now.
CPU usage is not noticibly higher than no huge transfer.

Maybe it's about changing some settings and try now?

stephenw10

So.... not using Mellanox NICs?

ogghi

@stephenw10 I am using the Mellanox cards.

I will most likely test to change settings here (again)

Suggestions?

stephenw10

I would certainly disable the hardware offloading there in case something isn't correctly supported under mlx.

Those iperf figures are through the firewall rather than to/from it?

ogghi

@stephenw10
YAY!
This finally is all good and fast now!

Iperf (with 10 parallel streams) shows (a bit bouncing but hey) 9.2Gbps as peak

I enabled HW TSO and HW LRO

Thanks for the support!

Also: CPU load is not much either. So ++ for the Mellanox cards!

stephenw10

Nice. Just to be clear you 'set' those options in the GUI, actually disabled them?

ogghi

@stephenw10 yes, this is how it looks now:

stephenw10

Excellent, thanks!
