Config question

Everything I said was an educated guess. The only way to know for sure how your setup will perform is to test it. Have a bunch of friends access it at the same time. Test transcoding streams, test non-transcoding streams, check CPU usage, check how fast transcodes are happening, check memory usage, check network usage, check disk usage. You can then extrapolate the max number of users you can support based on your tests.

Keep in mind that streaming, even without transcoding, is a pretty intensive process because of how time sensitive it is. And you have relatively modest hardware for such a large number of potential users.
