gigabit internet with Zotac ci323 Speed bottleneck

Recently, I was offered a good deal on gigabit cable (1000Mb/30Mb) internet here.

I wonder why fibre ISPs still have asymetric bandwidth. With coax and also ADSL, there were valid reasons for it. Not so with fibre.

@jknott what I got is coax. It's offered by cable company Rogers here in Canada.

Have you tried running iperf against the LAN port from a client on your local network? I run a CI323 also, just tested mine and got about 860Mbps UDP but only 350Mbps TCP. I also run snort though . . . not sure if that could plausibly impact TCP throughput significantly more than UDP. But the fact that disabling bandwidthD got you a speed increase of roughly 120Mbps would seem to suggest that your bottleneck is not necessarily the NIC. Have you monitored CPU and other resource utilization during your speed testing?

[chevywu]

CPU usage doesnt seem to be problem. It's always low (<10%).

Just ran iperf on TCP towards a local server:

Client connecting to 10.0.5.11, TCP port 5201
TCP window size: 64.2 KByte (default)

[ 3] local 10.0.5.1 port 41649 connected with 10.0.5.11 port 5201
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 844 MBytes 708 Mbits/sec

Just curious, is snort limiting your speed because of CPU usage?

Hi @JKnott

I found so much information from you and other contributors about pfSense on Rogers. Your response was very, very helpful.

I changed out my motherboard, NIC's, SSD and still my intermittent disconnects did not go away until I turned off gateway monitoring and gateway action. I also followed your other advice here in this forum on how to setup DHCP6, DHC4 on the WAN.

BTW, after all the trouble shooting, I am actually back to an old ASUS motherboard that has Intel Ethernet on board and then I have one genuine Intel single port stick in a PCI Slot.

I am thinking of starting a new thread regarding all my investments in a new motherboard (in the past 2 weeks) (AMD APU) with a dual Intel ethernet card installed.

Seems to boot but pfsense crashes within 2 to 3 days.

Any thoughts would be much appreciated.

Mark

That's quite an investment Mark.
For me, I think if I can't get close to 800Mb, I will probably downgrade to their 500Mb plan and save 10 buck.

Did you ever succeed in improving your download speed? I am also stuck around 550Mbs

[chevywu]

No, I didn't.
I feel it's a combination of both NIC and CPU.
So, I went with a full workstation setup with a i7 3700 CPU and a eBay fake Intel NIC.

In case you were wondering, i was able to get 750/750 working by tweaking it:

sysctl net.isr.dispatch=deferred AND Disabling the Kernel PTI workaround for Meltdown in System > Advanced > Misc.

Thanks for letting me know.
I decided to upgrade on HW mainly because I want the box to do more. IDP, bandwidth monitoring and Traffic shaping...
