I found a very good tool from Futubox, to test the download speed for Streams
for Info: Futubox has only HD Streams and very fast servers
now you thought about your problems can evaluate, with the HD streams

for Stream Speed ... http://speedtest.futubox.com/

for Internet Connection ... http://speedtest.net/

from FAQ Futubox:
Question: I can not watch it without stutter and freezing Futubox.
You need to have more than 5 Mbps download speed to our servers.
Actual, your speed can be checked here:http://speedtest.futubox.com

my speedtest results:
speedtest.net -> DL 12500 kB -> UL 2100kB ...... speedtest.futubox.com -> DL 500 kB

my assessment:
but I think 2 MB is enough, for HD Streams
and 200 kB for SD Streams

My link.
Real download speed=28Mbit/s (http/ftp/etc)
Fubox speed test=20Mbit/s
Still, most RTMP hd streams stutter on my player and work fine on my PC.
