Re: Wanted: Asia bandwidth test files

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.

Hi
I think RING project NLNOG has potential to help your effort.

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.

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!
