[Live-devel] live555MediaServer performance improvement

[Ross Finlayson]

> When I testing the RTSP server live555MediaServer then I faced slow performance. On one core of the CPU with a clock speed of about 3.2 Gz it is possible to process only about 140 client connections. The search for information on the mailing lists indicated the following ways of optimization:

There’s only one “mailing list” for this software: This mailing list.

To my knowledge, nobody has ever suggested that the implementation of the “DelayQueue” class needs to be improved (and, to my knowledge, the current implementation has no problems at all).  So that’s completely a ‘red herring’.

I my experience, scalability issues with our server software are usually caused by running up against limits in either (1) the capacity of their network, or (2) the number of open files (sockets) that are supported by the underlying operating system (see http://live555.com/liveMedia/faq.html#scalability ).  Increasing this limit usually solves the problem.
