Testing how Smooth Streaming chokes

Just for fun, I tested Big Buck Bunny being served through IIS Media Services from the local disk, running on an Amazon EC2 Micro instance (the smallest available). This is a fairly lightweight server, i.e. something you would never want to run in a production environment. Consider this the streaming equivalent of “Will it Blend?”…

The results are in – when it’s going well, it’s surprisingly great, and when it’s not going well, it’s terrible. 😉

Total Chunks: 2691
Chunks Tested: 2691
Manifest Download Time: 310ms
Avg Video Chunk Response Time: 357ms

Stream 0: video, 2962kbps, 2056kbps, 1427kbps, 991kbps, 688kbps, 477kbps, 331kbps, 230kbps
Stream 1: audio, 128kbps

Things go OK around 89% of the time. But when they don’t, it crashes and burns…


Yikes. You can almost feel the Silverlight players freaking out. 😉
