Comment(by bgamari):
Here's a simple throughput test confirming the plentiful amount of
bandwidth on the network,
{{{
[0921 b...@venus ~] $ time dd if=/dev/zero bs=512k count=100 | nc
mars.local 9999100+0 records in
100+0 records out
52428800 bytes (52 MB) copied, 48.8073 s, 1.1 MB/s
}}}
With another process running on the pulseaudio server,
{{{
[0921 b...@mars ~] $ nc -l 9999 | dd bs=512k of=/dev/null
0+69938 records in
0+69938 records out
52428800 bytes (52 MB) copied, 52.4389 s, 1000 kB/s
}}}
In short, the network can carry at least 8 Mbit/second. A raw audio stream
(48kHz, 24 bits/sample, 2 channel) on the other hand should require only
2.19 Mbit/second. Unless I am missing something, network bandwidth does
not explain the poor performance of network streaming in PulseAudio.
