OpenWebRX performance tests

OpenWebRX serving 10 clients simultaneously (and also running the browser windows on the same machine), without audio underruns.

  • Server CPU: Intel Core i7
  • samp_rate: 1024000

I had to increase the number of clients above 15 to notice the first underrun (although it was still usable).

Please note that digital downconversion (DDC) is a very CPU intensive task, and if you use OpenWebRX with the default sample rate, it can serve even more clients.
