I tried some experiments today:
First, a recap:
My system is a NAS (QNAP TS-110) hosting the squeezebox server R7.5.1
with a Touch also running 7.5.1
I have a wireless connection from the Touch to the router and a wired
ethernet connection from the router to the NAS.
With this configuration I sometimes experience stutter ("re-buffering")
at the startup of 24/96 FLAC albums. But never after the initial
"re-buffering".
Today I tried running the server on my desktop computer (2.8GHz Pentium
4 with 1.5GB of ram running Windows XP).
I never got a re-buffering with this setup, even though I was still
using the NAS as the music library.
So the desktop (hosting the SB server) was wireless to the router.
The Touch was wireless to the router.
The NAS (with the music library) was wired to the router.
So the music files on the NAS had to make it through one wired and one
wireless connection to get to the server. The server had to go through
two wireless connections to get to the Touch. But it worked perfectly.
CPU usage was usually below 50%, but sometimes did hit 100%.
Then I went back to hosting the SB server on the NAS, but tried moving
the Touch into the room with the router. Even though I was still
wireless, it seemed to take a bunch of tries before I got a
"re-buffering", but it finally did happen. The Touch was only a couple
of feet from the router.
Lastly, I tried a wired connection from the Touch to the router (and
still wired from the router to the NAS), so no wireless at all. I did
get one re-buffering at the very start of the experiment, but then I
tried many, many times without seeing another re-buffering.
So it appears that a combination of a low powered processor in the NAS,
combined with a wireless connection is causing the re-buffering (at
least in my setup). The NAS with a wired network seems like it would
very rarely, if at all have the issue. But the wireless network works
fine with the server on my desktop computer, even though I am using the
wireless path much more than if I use the NAS setup.
I wonder why the changes to the $outputThreshold setting don't seem to
affect anything. I don't see any difference (I don't think) when
changing the setting from 20 to 40, and changing it to 50 or 100
doesn't work at all (no music plays). Maybe the $outputThreshold
setting isn't working as expected?
It is possible that 7.6 release will help enough that my relatively
minor issue will be gone. I'll try it as soon as it is stable enough
for release.
