| Thanks for your responses. I will try Flash Player 8 and let you know. I
have not tried FP8 or Studio 8 yet. Do all clients participating in the
experiment need to be on FP8? Do I need to recompile FLA using Studio 8?
I was beginning to be convinced that it is the number of hops (there may
not be a magic number 15, but latency would be proportional to number of
hops). With South America we are getting 18+ hops, in the US we get 8 to 10
hops. We are considering hosting with Akamai ... they claim to have servers
closer to end points and claim to reduce number of hops. I was told they
will have their FCS hosting available in a month.
As far as firewall, proxies and other issues, I have checked with client
machines and they have no firewall, proxy, etc. In most cases the US client=
s
have firewalls, etc. And as I mentioned US to US latency is 0.5 secs.

Dario is right. It could be any number of things. But FP8 fixed some
latency issues due to a bug in the way we handle jitter. If you're not
using FP8, it wouldn't hurt to try it.
As for FCS/FMS having problems with more than 15 hops...I'm not sure
where that number came from. But that's the first I heard of that it.
