Jitsi iFrame API performance issues

#1

Hi,
I’ve been using Jitsi Meet iFrame API on my site, however now the connection is established quite slowly, and the video and sound are lagging. Here is my config:

       var domain = "meet.jit.si";
        var options = {
            roomName: room,
            parentNode: document.querySelector('#bigscreen'),
            userInfo: {
                displayName: m
            },
            configOverwrite: {
                prejoinPageEnabled: false,
                // startAudioOnly: false,
                startWithVideoMuted: false,
                enableNoisyMicDetection: false,
                enableClosePage: true,
                disableDeepLinking: true,
            },
            interfaceConfigOverwrite: {
                // DEFAULT_LOGO_URL: 'battery.png',
                'TOOLBAR_BUTTONS': [],
                SHOW_JITSI_WATERMARK: false,
                VIDEO_QUALITY_LABEL_DISABLED: true,
                CONNECTION_INDICATOR_DISABLED: true,
                CONNECTION_INDICATOR_DISABLED: true,
                SHOW_JITSI_WATERMARK: false,
                HIDE_DEEP_LINKING_LOGO: true,
            }
        }
        myapi = new JitsiMeetExternalAPI(domain, options);

What could be the issue, or what could I tweak in the options to mitigate the lag, and to make the connection establish faster?
