I currently live in Vietnam, I have also lived and worked from China for
US based companies. I am American and love to travel!
The problem may well be on your end. Some providers have bad
international peering. It is that simple. When doing mapping software
I had tons of issues accessing our source control system.. We went
round and round finally finding a provider that gave good connectivity
to all. I stumbled upon the answer while downloading a movie!
Bittorrent for the win.. I use uTorrent, and while in china getting the
usual crap download speeds, I noticed one peer nearly maxing out my
connection. uTorrent shows country flags by the peers, you see. I saw
a USA flag and a GREAT connection, and copied the IP address. Some work
with Whois and some dns digging, tracert showed the provider. It was a
home connection, but I called them anyway. They had another business
branch doing business/colo hosting. Most home providers also do hosting
because they have unused upstream. Always call and negotiate as they
must pay for it whether they use it or not. :) Unfortunately these
agreements change, so there is no permanent solution.
Or maybe the problem is on their end. Great Firewall of China, etc.
PCCW is the best gateway, you can get pricey (ie 3x-5x more than digital
ocean, or vultr) servers in Hong Kong with guaranteed bandwidth to the
middle kingdom.
And we have cable cuts, 4 for me in the last year. mostly south of Hong
Kong.
Anyway, expect to pay.. If you want business level quality of service,
they will treat you like a bank or brokerage, etc. No money, then take
what you can get!
Also, time of day matters. Nights, weekends are slow and saturated.
Rainy saturdays and sundays are the worst. 1/2 speed at best.

Hi, Maxim,
Thank you very much for your reply.
I was testing using OM3.3. I set up a server in California and I am
located in Boston. The client is located in Beijing, China.
I did a video call with the client. I can feel there is some delay. The
client can connect to the server at 2 Mbps speed and I can connect to
the server at 2 Mbps speed.
I don't understand why the video call still has obvious delay while
Skype does not have this problem (at least much shorter delay). I guess
this is because OM is not using point-to-point direct connection while
Skype is using point-to-point connection.
Is there any way I can reduce the delay?
I just installed OM4.0, but I have not tested it yet. Do you think OM4.0
is better than OM3.0 in terms of delay.
Thanks a lot!
Tom

Hello Tom,
Network testing tool measures the speed using Flash player,
So the speed displayed is the actual AV speed
What version are you testing?
PS please do not cross-post to multiple multiple lists

Hi, all,
I just set up a server for long distance video conference.
The client can download files from the server at 2mbps. However,
when the client uses the network testing of the OM, the speed is
only .02mbps. Any one knows why?
When we tested face-to-face video talk, I can feel there is some
delay.
Is that possible to tune up OM so that we can improve the speed
of OM?
Moreover, compared with other open source tools, how does OM
perform in terms of speed?
Is there any other open source tool better than OM?
Thanks,
Tom
