Just wondering if I could some international speedtest results on snap UFB 100/50. Been looking for some but I haven't been able to find any.

What about west coast USA? LA, California?

LA:



Have seen this much higher though. With 100Mbit you get much better throughput with multi threaded downloads (which speedtest does not do). I can easily get 12MB/s from the US.

Speedtest will do up to 4 threads I think...

They seem unusually high for International servers.

speedtest.net is often not particularly accurate, best to use a real world transfer.

Don't trust those speed tests. a single TCP stream to the US west coast is usually around 3mbps on even a $100,000 a month connection due to latency and TCP.

Speedtest by default runs two threads but providers can invoke up to 8 threads.  I have seen single thread speeds from a Canadian ISP limited to 3 Mbps by TCP settings (window size) get 18 Mbps from the same server on speedtest where 6 threads were enabled.  Downstream speedtest should be fairly accurate as it is just transferring large random JPG files but upstream tests can be less reliable.

Users of UFB services from providers such as Snap and Orcon have seen much better single thread speeds than 3 Mbps from many international sites but only if TCP is tuned for high bandwidth delay product (should be default on modern OS).  In addition, the congestion will vary by ISP and time of day.  A setting that can have a big impact is Selective Acknowledgement (SACK) as if it isn't enabled (client or server) any minor loss event will have a much greater slowdown impact on TCP.

Based on posts late 2012 (see SNAP forum section for postings on "WOW! Got International Bandwidth!?" and "UFB Poor Performance" with last post Jan 2013) SNAP users were getting high international speeds once an interface issue with Chorus was sorted.

This is a complex topic as there are many elements involved and I have yet to see a good answer on how to measure the international traffic performance of an ISP.  There is only limited bandwidth into NZ and even users with different more aggressive TCP algorithms can supress other flows, potentially giving one happy user and one unhappy.

WHat sort of speeds do people get using speedof.me?

I'm busy doing a big upload so can't do any tests ATM.

speedof.me is an interesting tool, with real time feedback, but has some limitations for this check. It seems single threaded so may not show as fast as speedtest.net (but does relate to real world).

Being CDN based it is likely it will only measure to Sydney - source is shown on the graphic - and I don't know how it could be used to any other destination. International speeds to the US seem to be a significantly bigger issue than to Australia which is understandable due to the higher delay (extra 100ms - harder for TCP). I wait with interest for results.

I'm on UFB 30/10 and international speeds are great. Quite easy to max out my line, with a single thread. Below is a download of a linux ISO form California, US @ 3.2MB/s on WiFi.

I can max out my 100Mbit USB connection to a NZ based server but with real world transfers (rsync/HTTP) from the US I see a max of around 2-2.5MB/s.

Pulling that same file just now shows around 1.8MB/s;

People shouldn't expect to max out 100Mbit/sec on UFB for a single connection.

The real reason to buy 100mbit is for total aggregation of a lot of users, not for a single user.

There are many websites that will never give you 100mbit/s downloads, and thats normal.

Indeed, I'm trying to show that that's not what actually happens.

most web sites hosted overseas are on gigabit connections, but tcp/ip ramp up can take a few seconds, and most web browsing won't go that fast for throughput, but having a faster connection can mean that you're mostly sitting on application bottlenecks as it should be.

things like php, databases etc can really slow down web sites.

and it's not unreasonable to expect 100megabit/sec to australia on 10mb files i reckon.

with linux, i've noticed that using more recent kernels (3.8 etc) on the sender can improve throughput, and on the receiver having at least 3.0 kernel can help.

also sometimes tweaking /proc/sys/net/ipv4/tcp_rmem can help.
