AVPresence component performance

We have been working at testing a virtual meeting room based on the AVPresence component that came with FMS developer edition and have had some good results.

We had some very promising tests with participants across the country and even from Africa and Europe having very useable experiences.

But we have also experienced inconsistant performance including audio being out of sync with the video (by 10 or 20 seconds), the video displaying in "slow motion" or some participants experiencing long delays in receiving the video/audio stream (30 to 45 seconds) between one person asking a question and the other participant hearing the question.

Some of the longest delays were to participants in Brazil (the FMS is located in Canada) but we also saw unexceptable performance to computers on the same network as the server and also to some participants using the internet cable provider as the server is connected to. The problems have occurred with only 2 or 3 connections so it is not running into the 10 connection limit on the developer license.

Are these poor results simply some of the "limitations" built into the developer edition ? Or are we going to continue to run into serious user experience issues once we move to a fully license FMS?

    FMS components were not create to have best performance so you should never rely on a FMS component in a commercial product... The worst component is probably the connection light that will call server a the interval you set this is a major issue (you should call server only when you need this data). Developer license is the same as the full license.

    Your delay can from a lot of things for each client : slow computer, slow internet connection, firewalls, upload and download limits, flash player version, OS platform(sound echo on Mac when sound kHz is under 44), ...

    From server side : Ram size, CPU power, do you use FMS and your Web Server on the same computer, bandwidth size allow, are you connecting directly to the RISQ network(in Canada)...

    Delay that you obtain is to long, is absolutely NOT NORMAL for sure. Sometime, from my experience, problem is 30 inch in front of monitor... so try the same test with a competent technician...

    If computer on the same network in the same location had poor results problem is probably from your network or your server...

    post more technicals informations if you can!
