Generally speaking the 1.8.0 is a solid release. I haven't encountered any problems or issues with the server whatsoever.
However, I have noticed that there is a MAJOR lag between the time the signal is streamed and the time the listener hears it at the other end. Pre-1.8, I observed a lag of no more than about 45 seconds. With this new version, that number easily goes as high as 2 minutes. (FYI, the buffer position for my test listener varies between 137000 and 153000 -- a lot more than the reported average of 128000)
Was this an anticipated result of the better synched title updates? (Speaking of which... those title updates are VERY reliable and work very well!)
This buffering issue is not a problem for me... I was just curious to seee if it was something that was expected.
