New SG-3100 with gigabit comcast line... can't get over 540Mbps

How is your WAN provisioned? DHCP? PPPoE? Static?
-
I'm pulling the WAN IP via DHCP.
The server doesn't matter. After 10+ tests with different servers, the results are all pretty much the same.
Like I said before, straight out of the box default configuration yields the same results.
Any ideas are appreciated.
Thank you,
Ed

From your public IPs you listed there in your 2 tests - your clearly on a different ISP segment when your slower vs the segment your on when your faster.
So it is possible its your isp. I would suggest for a valid test take your isp out of the equation. Why don't you put box on the wan side running iperf, and a box on the lan side and do some testing that way, etc.
have a 3100 here, but its in production - and would get screamed at for taking it down for a test ;) Sorry but our connection here is not gig, so I can not just do a speed test to show getting gig, etc.

I figured out what the problem was... and it had nothing to do with the Netgate SG-3100!
Speedtest through the SG-3100 now....
The issue was that another gigabit 8-port switch was in between my main machine and my core HP ProCurve switch. It simply could not handle the sustained throughput.
Once I connected my main machine directly to the core switch... viola... issue gone.
Shame on me for not testing better (and being consistent with my test machines) before posting. I should have done better apples to apples testing. I'm sorry to bother the group with a bad post.
Hopefully others will see this and know that those little 8 port gigabit switches can't really handle gigabit sustained traffic and they should really test everything before posting.
Mea culpa,
Ed
PS: Does anyone have a favorite Bootable USB linux distro that has some nice network testing tools built in like iperf? I'd like to add it to my toolbox.

Nice catch. I would not have expected that. Even from the lowest of low end switches!

Please name names.
What switch was that? -

What switch was that?So.. I tried two...
The worst one (in the original post) in terms of speed was the Trendnet "GreenNet" switch model TEG-S81g (HW v2.0R) with 514 Mbps.
I then tried a non-green 8 port switch from Netgear- one of those "business grade" units with a metal box and probably lead weight inside. Model GS108-400NAS. It yielded slightly better- around 580Mbps.
Hope this helps.

Thanks. Trendnet and Netgear are some of my all-time favorites.
Was kind of hoping you'd say TP-Link though. :)

TBH, I was surprised too! I've had really good luck with Netgear and TPLink switches.

Thanks for the info. I have a TEG-S80g. I'll need to keep this in mind if I ever get gig internet.

My 3100 has been rock solid running Comcast Gig. Make sure you test with [speedtest.xfinity.com], it will use a dedicated server that is always able to do gig, when you just use speedtest you use other peoples servers, and most of the time they dont have gig bandwidth.
I did have weird issues with my modem firmware causing slower speeds, but they appear to have fixed that. What modem model are you running btw?

I'm running a Motorola MB8600 (32 channels down and 8 channels up). Total speed demon and very reliable. Only thing I wish it had was more than one port. (It actually has 4 ports, but three are masked off- for use with bonded connections only).
