Hi,
We don't publish official performance results, but we have seen over 4000
concurrent live streams (low-bitrate) served using an XServe QTSS server.
Your performance is largely dependent on the bitrate and size of the movies
used, and the transport that the clients are using. Also, reflected streams
use less CPU and RAM than on-demand streams.
If you're planning on deploying DSS and are interested in what kind of
performance you can expect, I would recommend running some scalability tests
for yourself. We include "StreamingLoadTool" which can be used to simulate
large numbers of client connections.. but you will have to run several
concurrent instances of the program, probably on multiple client machines.
With DSS, you'll probably need to optimize the OS some in order to achieve
the best performance results. You can also tweak the DSS
streamingserver.xml file to improve performance.
Please let us know if you need help using StreamingLoadTool or other
questions regarding performance/scalability.
