Is anyone else seeing poor speeds from/to the US? It was really noticeable last night trying to update my test OPNsense instance - package downloads were going at a snails pace (LeaseWeb San Francisco mirror). NPerf speed tests are to the 2D servers in Auckland, Sydney, and LA.

US - 26/08/2022 23:04 NZST

US - 26/08/2022 22:49 NZST

US - 26/08/2022 02:56 NZST

It doesn't seem related to US latency issues as the slowest speed test also had the lowest latency. NZ is fine. AU was also having issues last nite, but looks like it has been fixed.

NZ - 26/08/2022 22:45 NZST

AU - 26/08/2022 02:57 NZST

AU - 26/08/2022 22:47 NZST

Compare this to a speed test back in March and the drop is significant - 87% on download and 60% on upload.

US - 31/03/2022 12:22 NZST

Nope, I am getting ~900Mbit to the US on 2degrees currently so this is 100% just you.

Since you're using Windows it is highly likely you're running into the "classic" rubbish state of Windows TCP tuning. Follow though this: https://www.geekzone.co.nz/forums.asp?forumId=66&topicId=239862

If you're using Windows open up the Command Prompt or Powershell under Administrator mode and type the following:

netsh int tcp set global autotuninglevel=normal

Then reboot - see if this improves your speed.

It may be worth mentioning what router you're using too. And booting into Linux and testing via that.

Seems fine on 300 / 100, 2degrees fiber.

Depends what you mean by bad. I certainly do not get line speed (am on 900/500), or even close to it. I seem to get a bit over 200Mb/s to most US servers (randomly selected) on speedtest. But then got a good result to Wave in San Francisco of 534/153, though the latency was shocking to this server compared to other US ones 🤷. Couple of other tests got similar results as well. Im certainly not unhappy with the performance as I dont expect line speed internationally.

Guess it might depend on location as I think others who have replied are Wellington. I'm in Auckland. And of course the test server selected.

FWIW: Ive tested from a wired linux host (and also wireless and get same results but my wifi is good). I get line speeds to various NZ servers.

So I don't think its necessarily "just you" - could be a bunch of things.

As a comparison to Timmmay, I tried the same Eugene, OR server.

First result was pretty terribad:

Tried again then got:

I put that difference down to being "just the internet".

Well aware of the Windows tcp stack "features", and autotuning was already set to normal.

Connection is 1000/500, in Auckland. Router is pfSense 22.05 on ESXi 7.03U3c. Host is an i5-4570, 10gig everywhere (although gig to the ONT of course) with the path going through a Dell 8024F and a Mikrotik CRS309-1G-8S+. iPerf routed/inter-vlan is 4.3gbps, switched/intra-vlan and to the pfSense subnet gateway pegs at 9.9gbps. I had also switched things over to an OPNsense 22.7.2 instance I've been testing, with no significant change.

Getting 900mbps+ to the AKL and SYD 2degrees nperf servers. Speedtest.net via Chrome 880 and 750 respectively. Speedtest native CLI on Ubuntu 20.04 was not significantly different to - 800+mbps from AKL and SYD. But was significantly slower from LAX and SFO.

@nzkc: by bad I mean 80mbps peak/52mbps max average yesterday, vs 468mbps peak/391mbps average in a test I ran back in March. Your first test results looks about what I was seeing, although it was consistent rather than just a one off.

Good news though, something seems to have fixed itself overnight. At least for now.

looks like it would have been an upstream issue which they have now resolved without any action on our side.

as the internet is a whole lot of interconnected networks, these sort of things aren't always in our direct control.

if it happens again, let us know, but geekzone isn't the fastest way if it is something urgent, best to call up.
