I installed wireshark but I'm having problems getting it to report what I want. I'll keep banging on that. I recorded and graphed the time it takes to send each buffer (16K in this case) against the buffer-fullness of the squeezebox. The send time jumps all over the place, starting out very fast and then staggers between a very long time and fairly fast, presumably because the squeezebox is frequently quenching the flow until it wants more. The x axis is milliseconds, the y is nanoseconds. 28223 Smoothing 10 values on each side, a pattern of fast-to-start, then leveling out is visible. 28224 The main point here is that things don't get dramatically worse at 19000ms. Which is interesting, because here's the graph of the squeezebox's report of the buffer fullness, measured at intervals (hence the steps): 28225 It looks to me as if the squeezebox is in fact reading the TCP stream more or less steadily (once the buffer is full) - but at a certain point is just stops adding what it reads to the squeezebox's play buffer in any sort of timely fashion, and what it has just gets used up in a more or less linear fashion. Before that point, the server is clearly having no problem keeping the squeezebox fed. Once it starts stuttering, the fullness bounces around between 0.0 and 0.04, if that. These graphs are fairly typical, but I've seen at least one case where the problem, whatever it is, happens right near the start, and the buffer gets maybe 0.07 full and then rapidly slides down to 0. When the stuttering starts varies, in other words, but near the beginning and towards the end seem the typical cases. Insight welcome. This is slowly driving me mad. +-------------------------------------------------------------------+ |Filename: fullness.png | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=28225| +-------------------------------------------------------------------+ ------------------------------------------------------------------------ ScottAM's Profile: http://forums.slimdevices.com/member.php?userid=69412 View this thread: http://forums.slimdevices.com/showthread.php?t=110986 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
