Could anyone estimate how much data volume would being connected to kaya, for example watching games, consume per unit of time?

I havent dont formal benchmark, but its not sizeable. You can try running chrome and checking the network tab. Im sure there are other tools outthere to check the activity if you are looking for a specific network condition affecting your particular connection.

Less than 5KB/s... usually under 1KB/s

So about 4MB/h.

Thanks.

How did you calculate that? There is no way its even close to that.
90% of the timethe usage is 0kB/s

1 KB/s seems like a reasonable guess. Remember, the game isn't the expensive part; the server also needs to be polling via some mechanism for new observers, new chat, user status updates, and other errata. The bandwidth usage over time mostly depends on how that polling (or perhaps pushing, in recent browsers) is implemented and how real-time they care to make it.

More than 5 KB/s is hard to fathom, but 1-2 KB/s seems plausible.

In modern browsers, I believe they are using websockets, which don't require polling per se. So they can push the presence of a new player to your client using just a few dozens bytes of information, without including HTTP headers.

This is an important question for those of us who have to live without much bandwidth at home. Many sites simply don't work for us, less because of needing a lot of patience (minutes while the next page loads) than the site not detecting the slow connection and so not adjusting timmeouts accordingly (site thinks you've gone away but you haven't responded because site is still sending you the page).

You think a couple thousand bytes per second is nothing? At 28.8 Kbaud (phone line on a good day) the throughput is only about 3000 bytes/second.

It's also important if considering to connect using the phone line while on a trip with roaming fees between 2.5€/10MB (Europe) to about ten times that.

Did you log onto Kaya and monitor the network traffic or not? It is almost never exchanging data on the main page. 1kB/s continuously is a huge over estimation. I looked at the network usage for the connection myself.

Just tested bandwidth with Little Snitch on OS X, main beta site page plus watching a game:

TCP Port: http (80)
Total Traffic: 221 kB up, 1,09 MB down
Connected: yes
First Activity: 15m 03s ago
Last Activity: 13s ago
Connects: 53 successful, 0 blocked

Download doesn’t change much after the first loading of the site.

1 MB over 15 minutes is about 1Kb/s

Well, if most of the download is just loading the page initialy, then over a longer period of time it would average to a much lower number. The initial loading is always going to cost about the same, so it definatly more cost effective to only log in if you have enough time to justify it
