Is there a way to diagnose poor network performance?

Postby jseims » Wed Oct 17, 2012 2:12 pm

In my test code, if I just publish and subscribe to my own stream, the subscribing flash player shows video that lags by about 5 seconds and plays at about 1 frame per second.

My network speed tests are fast, so is there any further diagnostics I can perform that would explain this performance?

For what it's worth, the performance was fine a couple weeks ago.

Also, it seems to happen if I don't provide an IP for session hints. I'm creating server-side sessions from Amazon's us-east-1b region, and my web browser is in San Francisco.

If I provide my browser IP address as a session hint, the performance is better. But I have misgivings as to how good performance will be when others (perhaps outside SF) join.

Hey Josh,

For some context, are you using a p2p session? Can you give us a sessionId and an issueId for a little debugging? (To get an issueId you need to Ctrl/Cmd+Shift+Click on the white tokbox logo in the top left corner and it should pop up a new window with the info). Infact, if you just copy and paste the whole popup and all the details and post them back here we can look into it faster.

I'm not using a p2p session, as I want up to 6 people to be able to chat at once (maybe this number is too ambitious?).

My issue number is 9FDC9EA33FE6D179A9BACE49804DB45B, and my session id is 1_MX4xNDIyMDYwMn45OC4yMTAuMTY2LjI0MH5XZWQgT2N0IDE3IDE1OjUxOjQ5IFBEVCAyMDEyfjAuMTE4MzcyNTZ-

If it helps, sometimes the performance is fine. Like right now it's fine, with

issue id: 97B1289B7D555FCB6EA220F9A8708005
session id: 1_MX4xNDIyMDYwMn45OC4yMTAuMTY2LjI0MH5XZWQgT2N0IDE3IDE2OjM5OjI2IFBEVCAyMDEyfjAuOTk0MzQ2MjZ-

I am not familiar with this area, but I also think sometimes the performance is quite fine.

Josh,

Thanks for the updates. I will take a look at what we can find using the issue ID and session ID. Sorry about the delay in response, I was in the area affected by Hurricane Sandy so I wasn't able to regularly check on support requests.
