I've been running wowza on an EC2 small instance for about a week and it's been great - it performed better than RTMP from CloudFront. I've been streaming dynamic bitrates, and typically serving the highest levels. However, today the bandwidth has dropped off dramatically. My lowest bitrate is about 500kbps, and my bandwidth today is consistently dropping below that for me. Obviously, this could be an EC2 bandwidth issue, but I'm wondering if there's a way I can know if my instance is performing poorly. I've stopped and started the server a few times, to no avail. If I reboot my instance, will I lose the configuration changes I've made and have to reinstall the server license, etc?
From past testing and customer experience, we estimate that the m1-small, large and xlarge instances get about 150, 250 and 350mbs throughput. We don't have similar experience with the other instance types that have been added more recently.
