Wanted: Asia bandwidth test files
Hi, I'm sitting on what is advertised as a 100mbit/sec connection in Cambodia. I have been trying to verify that, because I do not believe it is valid. I did iperf tests from a number of network locations, and at one point I did get 71mbit/sec (most of the results were around 20-25mbit/sec or less). But I dont think 30 second iperf tests are particularly revealing when the bandwith rate might change drastically over the day. I considered doing a 3 day iperf test, but somehow this seems not how the tool was designed. Someone suggested I find test files from various Asian locations to download via wget. I found a bunch of 100mb test files for various providers in N. America and Europe on webhostingtalk, which were interesting, but I never got more than around 5mbit/sec with them. Does anyone have any machines in Japan, S. Korea, or other asian locations with good bandwidth. where they can host a 100mbit file so I can attempt to download it to test this? Other suggestions for reliable tests would also be welcome! Please, dont suggest some flash garbage :) thanks! micah --
Linode hosts one to test their Tokyo location - http://speedtest.tokyo.linode.com/100MB-tokyo.bin Source - http://www.linode.com/speedtest/ On Thu, Aug 2, 2012 at 1:59 PM, Micah Anderson <micah@riseup.net> wrote:

Hi I think RING project NLNOG has potential to help your effort. https://ring.nlnog.net/ At least they have location in tokyo. And I talked with Seichi Kawamura who is leader of JANOG about method of quality verification among the world wide. They are using host of Softlayer, amazon and OVH which could select the location. Job and Mucho ccing. Regards, -Shishio (2012/08/03 2:59), Micah Anderson wrote:

If you can, I suggest finding other well connected hosts and using IPERF in UDP mode for your testing. Separating TCP long-fat pipe and slow start issues from true packet delivery/loss rates at a given bitrate are beneficial. Use Linux as most iperf windows builds are based on cygwin and have issues at higher bitrates. On Mon, Aug 6, 2012 at 4:10 PM, Shishio Tsuchiya <shtsuchi@cisco.com> wrote:

Hi Micah, You could try mirror.aarnet.edu.au, if Australia is sufficiently Asian for you...

Hi Micah

you may try downloading from stingray.cyber.net.pk It's in Karachi (Pakistan) with GigE limits. Use rsync. Regards, Aftab A. Siddiqui. -- Regards, Aftab A. Siddiqui
I find the mirrors here are generally beefy https://launchpad.net/ubuntu/+archivemirrors Thanks. On Tuesday, August 7, 2012, Aftab Siddiqui wrote:
