Transatlantic speeds?

dragon2611

Just wondering what sort of speeds most people would expect between the UK > USA on low end providers.

I seem to be getting between 10 - 40Mbit between a machine in colocker and one in dacentec.

Route looks to be via Level3

Wondering if this is typical or if someone's running their transit hot.

Times will be in GMT.

Edit:
The shorter intial transfer was me SCPing a smaller VM across, the longer sustained transfer is Syncthing syncing some VM dumps to the Dacentec server.

It will highly depend on the network. No idea about Colocker, but you shouldn't expect much from Dacentec.

But I see you're getting 40 MB/s, not mbps? If so, that's reasonable. Open multiple threads if you need more.

Id say 20 - 60mb/s would be expected (assuming gbit, otherwise ~12mb/s, capped at 100mbps).

Ive done a bit of transferring transatlantic (usually ~20GB disk images) and thats normally what we see (depending on time, and network providers at both ends).

It's 40Mb/s as that's an interface graph, I could see why that would be confusing as it's not explicitly stated.

Not that I'm overly bothered given the distance and the price I'm paying them both.

So 260 Mbit max, 200 Mbit average

If you need to move massive files around often, consider using specialized tools like WDT. Facebook claims to reach near theoretical link speeds.

Now that does look interesting, thanks might have to have a play sometime.

40 MB/s sounds about right, 40 Mbps would definitely be quite low. I never knew about WDT either, thanks for that link also! Will have to look into it for large backups and other data transfers.
