thanks again

    Wow thank you, Maxim, it's exactly what we were looking for and
    searching how to do it.
    Seems in new documentation there is no mention of this
    possibility, but now I've found it.
    Thanks again for help!

    Unfortunately network is the bottleneck for video conferences
    One can play with parameters in config.xml to decrease video
    quality and reduce bandwidth per user

        Good morning!
        So we are going quite well, we have virtual server 2-core 2GB
        RAM (VPS digital ocean)
        and for now maximum we did conference with 6 participants and
        smallest video, 4 of them were in Italy, where internet
        connection is really really bad.

        here are the highlights:
        0) they have bad performance with CentOS 6.5 VM
        so they got
        1) physical server HP DL380 G5 with 4GB RAM and 2x 4-core
        CPU Intel Xeon X5450 (3 ГГц). Gigabit Ethernet
        2) CentOS 6.6 Final x64
        3) OM 3.0.4-SNAPSHOT with all dependencies and third-party tools

        as a result:
        1) CPU was loaded up to 55%
        2) Outgoing network utilization on server was 71 Mbit/sec
        3) 15 participants were on network with bandwidth 50
        Mbit/sec and it was totally utilized

            Hi Maxim, do you know how the Russian team tunned the

                Actually we have report in Russian mailing list
                about successful conference with 18 video windows:
                16 with video 240х180 and 2 with 640х480.
                They have tuned both server and network

                    I will try next time, we chose this video format
                    only because were not sure if server can hold 5
                    of us.
                    Yes CPU usage was high, my laptop is i3-2367M
                    @1.40 Ghz, RAM 8 64bit
                    but when testing OM, I've shut down all
                    applications to see "pure" result.

                    great! if any day you need additional testers
                    we'll be happy to help

                        Hi, Maxim,

                        We've tested with 3 users and large video
                        (640x480) with our server and demo-server.

                        Ubuntu Studio preemptive kernel 14.04 with
                        Chrome
                        Windows 7 with Chrome/Firefox
                        10.9.5 Mac OS Chrome/Firefox

                        Results are:
                        for Ubuntu Chrome doesn't create any problem.
                        for Mac OS same, when entered with Chrome
                        sound went a little low for both of us.
                        for Windows Chrome creates delay of 6-8 sec
                        and sound goes very bad, instead Firefox
                        doesn't give any problem, real-time.

                        On your server is exactly the same. 8 sec
                        delay for windows with Chrome.

                        Last time 2 of our other participants were
                        using Mac OS with chrome and couldn't
                        activate video (in conference total 5
                        users: 4 video 90x120, 1 audio) and sound
                        was disappearing to one or to other. When I
                        asked one of them to test later with
                        firefox it was working, chrome still was
                        giving same error.

                        Hope it can give you some meaningful
                        information,
                        thank you again,

                                Thank you Maxim for looking into
                                it, if for you works fine,
                                probably there is other reason
                                than chrome.
Yesterday I was also trying to use Chrome (from Windows) to
                                participate in OM with 5 other
                                people and it was causing
                                problems to everyone - people
                                were not hearing each other, room
                                was getting stacked, as soon I've
                                changed to firefox, there was no
                                problem anymore.
                                Unfortunatelly I cannot provide
                                specific steps - the only thing I
                                am sure, it was not problem of my
                                internet connection and also our
                                server was stable (droplet 20$).

                                I am not expert in video/audio
                                conferencing, is it true that if
                                one person has problem with
                                bandwidth - everyone in the room
                                suffer? eventually if there is
                                any setting that permit us to
                                isolate one with problems so
                                others are not touched?

                                    Seems that last version of

                                    strange problem for users of OM,
                                    instead of video it shows in
                                    conference an tv-like
                                    interferences and sound is
                                    going on and off.
                                    Firefox works fine. Also
                                    previous versions were going
                                    well.
                                    I don't know what can be the
                                    reason, probably flash
                                    plugin, but if you have no

                                    attendees, ask them not to
                                    use last version of Chrome.
