SG-1000 throughput slow down
-
Hi,
I’m getting some strange speed test results when using my SG-1000.Running some internet-based speed with the SG-1000 in place I get:
speedtest.net 98 Mbps fast.com 97 Mbps google search page test (M-Lab) 8.4 MbpsWhen I connect directly to the cable modem I get:
speedtest.net 98 Mbps fast.com 97 Mbps google search page test (M-Lab) 97 MbpsI also see the slow down when using NzbGet with it toping out a ~4MB/s going thought the SG-1000 and ~12MB/s when bypassing it.
What would be my steps in finding out why I’m getting slow throughput on some sites / traffic
EDIT:
doing a speed test from the SG-1000 I get:[2.4.4-RELEASE][root@pfSense.localdomain]/root: fetch -o /dev/null http://download.thinkbroadband.com/50MB.zip /dev/null 100% of 50 MB 306 kBps 02m47s~2.45Mbps is far from the ~100Mbps i should be getting
EDIT 2:
Did some more testing, I only have a windows laptop available, so I wrote a little powershell script$fileSize = 10 $Request = Get-Date $null = Invoke-WebRequest ('http://ipv4.download.thinkbroadband.com/{0}MB.zip' -f $fileSize) # $null = Invoke-WebRequest ('http://client.akamai.com/install/test-objects/{0}MB.bin' -f $fileSize) $timeSec = (NEW-TIMESPAN -Start $Request -End (Get-Date)).totalseconds $speed = (($fileSize / $timeSec) * 8) Write-host ("File Size: {0} MB, Time: {1:N4} s, Speed: {2:N2} Mbps" -f $fileSize, $timeSec, $speed)Running this script a few times with just the laptop connected to the cable modem then with the SG-1000 between them I get:
http://ipv4.download.thinkbroadband.com/10MB.zip direct to cable modem File Size: 10 MB, Time: 6.6559 s, Speed: 12.02 Mbps File Size: 10 MB, Time: 6.9133 s, Speed: 11.57 Mbps File Size: 10 MB, Time: 7.5968 s, Speed: 10.53 Mbps File Size: 10 MB, Time: 7.7176 s, Speed: 10.37 Mbps http://ipv4.download.thinkbroadband.com/10MB.zip throught SG-1000 File Size: 10 MB, Time: 32.3872 s, Speed: 2.47 Mbps File Size: 10 MB, Time: 29.7474 s, Speed: 2.69 Mbps File Size: 10 MB, Time: 33.5248 s, Speed: 2.39 Mbps File Size: 10 MB, Time: 20.5034 s, Speed: 3.90 MbpsNow I know my cable connect is not giving me the ~100Mbps that speedtest.net and fast.com report, but it remains to as why the SG-1000 throughput is bad?
What else can I do to get to the bottom of this problem?
Regards,

@jammcla with regards to: SG-1000 throughput issue did you ever get this fixed?
Look like i maybe having the same issue.

Are you able to get the full 100Mbps downloading that test file from thinkbroadband without the SG-1000 in line?
You might try a different test file if not.
You could also try speedtest command line client directly on the SG-1000:

@stephenw10 thanks for the reply I'll try the speedtest cli client, see my edit 2 for what I did try so far.

Running the sppedtest-cli gives me:

will have a look to see if/how I can run the speedtest-cli on the windows laptop.

When running the speedtest-cli (in python) from the windows laptop everything looks fine, but I still get a slower throughput when downloading files i.e. http://ipv4.download.thinkbroadband.com/100MB.zip

You might check to see it's some sort of flow control issue. The easiest way to test that is to put an unmanaged switch between the SG-1000 WAN and whatever it's connected to if you can.

and don't know if it helpful but under Status / Interfaces

Hmm, that does seem to be an unusually high number of OUT packet blocked on WAN.
Do you see that number increase specifically when you run a test that is slow?
Do you see traffic blocked in the firewall log?
Are you running anything that might be blocking that like Snort or pfBlocker?
Steve

I'm not running anything that I can think of that would be blocking traffic, I have defaulted the SG-1000 as part of trying to work this out so unless there something in there by default.
the blocked out packet don't move when doing a speed test.
looking at the logs I have a few noisy devices (another rabbit hole to chase down), but most of the traffic look like android devices phones, tablets, tv, etc...
what log does the out block go to? looking at /var/log/filter.log I only see block on the in?
any who, here's a dump from the gui, if it helps.

It depends what exactly that is and what logging is enabled. The fact it's not showing as blocked in the firewall log by the default block rule implies it's either something that's blocked by the firewall and not logged or it's something that's blocked for some other reason like it's malformed packets.
The fact the number doesn't increase during the test implies it's probably not the cause there though.Those blocks that are shown are all out of state TCP packets and they all have destination port 443/80. That is some client acknowledging the closed TCP session after the state has been closed. Not something that should ever cause a problem.
Try running at the command line when you are doing the test
top -aSH. Hit q to stop during the test and you can copy-paste the output here. That should show if you're hitting CPU limitation somehow.Steve

No, 52% idle looks fine. It would be good to see what is using the CPU though.

Hmm, nothing much happening there besides the NIC interrupt load which is what you would expect. Definitely not CPU limited then. What sort of throughput were you seeing when that was shown?

Don't know if this would help, but I found a file with in my ISP network that gave me near top speed for testing.
I now get only ~3% idle cpu and a ~27% reduction in throughput instead of a ~76% reduction when testing

-
I have tested the SG-1000 to at lest 125Mbps so I would not expect any reduction on a 100Mb line. At least not limited by CPU.

Thank you @stephenw10, do you have any suggestions on what I can try next to figure out why I'm seeing a reduction in throughput?
Do I need to capture traffic logs? I should be able to do that on the laptop.
