It is possible that you experience quite a delay when you're streaming your eyeson call live on Youtube. This buffering, which is caused by Youtube, can't be eliminated completely but it can be improved.
Please note: your viewer in Youtube won't notice the delay since your video, presentation and voice are in sync. It is just delivered by Youtube a little bit later. The only one who actually experiences the delay is you.
However, we completely understand if you still want to avoid such a delay. Therefore, go to your Youtube Live Stream Settings which looks like this:
Then, enable Ultra low-latency which is highlighted in the red box above.
