Re: [slim] Re: Network Activity

I am basing my observations on the fact that the network lights on my
hubs and server are always blinking like mad


IMHO not the most precise of benchmarks :-)


an I can see a marked
difference in the speed of my network if I unplug all of my
Squeezeboxes. It seems to have gotten much worse since I went from two
Squeezeboxes to four Squeezeboxes.


This is strange. I'm using five boxes, four of them wirelessly at 54Mb -  
and do surf, print and everything on the same network. You're talking  
about 1000Mb, 20x my bandwith with less players. There must something be  
wrong.



The server I am running, runs on linux and if I check dmesg there will
be hundreds of lines of server contacting each of the various
Squeezeboxes in just a few seconds.


dmesg is about boot messages, isn't it? I can't see anything slimserver  
related in there.


Could you do some actual measures? Please try netio or something to give  
some numbers.

 If all 4 are streaming WAV at 1440 KB/s, with extra bandwidth

 handled by a gigabit network with plenty of room to spare for Internet
 and file transfer activity.

Wrong order of magnitude :)

WAV is 1400 Kb/s, 176 KB/s.

I think that dmesg is used for more than just boot messages; it is
general kernel output.  I used it a lot trying to get a myth box up,
and it includes lots of module output during normal runtime
operations.  In fact, there's a wikipedia page on it:

 It also was much worse when I had them all synced. I could hardly use
 my network at all with four of them synced.

 I am not using the clock or any screensaver and my network is a
 1000BaseT.

I'm not a linux expert, but I'm sure there must be a ton of tools out
there that show you real-time throughput.  As pointed out by others,
the actual data transfer requirements *should* be way under your
network maximums, so if you can measure the throughput as you connect
/ disconnect squeezeboxes, you can figure out if anything strange is
going on.
Then you can use something like Ethereal to pull it all apart, or at
least to post a log of traffic from one SB for others to look at.
