We're currently doing some tests FTP'ing a large file (3Gb) to the US, and are getting very mixed results in transfer time.  Some tests have taken 2.5 hrs, others have taken as long as 5 hours.

Our bandwidth to the internet is sufficiently large that the time - purely by calculation - should be lower, certainly a lot lower than 5 hours.  Our ISP says this wide variance is purely down to international web traffic, but I'm surprised to see a) such big differences depending on when it's being sent, and b) it taking as long as it's taking anyway, even at the shortest time of 2.5 hrs.

Has anyone else with decent size internet pipes (say at least 5Gbps upload), got any experience sending large files to the US?  If so, I'd be interested to know what kind of time it takes.

Thanks in advance.

Of course I actually meant 5Mbps upload speed, not Gbps.

Pretty sure he meant to reply to a different thread.

Anyway what type of connection do you have?

Generally the only way to get guaranteed speeds is to buy a point to point dedicated connection.

Normal connections are subject to best effort delivery, your ISP will punt your data upstream and hope it gets there.  Congestion, contention different routes the speed of the server at the other end and their connection all have an effect.

There are many reasons download and uploads go slow and from NZ -> Overseas its usually due to the Bandwidth Delay Product (

This says in basic terms the high the latency you have over the same capacity connection the slower it will go with TCP Transfers. NZ is on a Long Fat Pipe to overseas.

In real terms.. if you want to get faster speeds then do multiple connections at the same time.
