There was several items in the last months about Slimserver hitting high
CPU usage and locking out players and browsers, and I have heard little
since. I am still periodically getting this problem despite using a
recent nightly download to drive a new Sqbox-G. I even looked in
bugzilla and couldn't find any references, although I thought it had
been taken on as a major bug. Can someone reassure me that this is at
least being reviewed because it seems to be a serious problem for many.
SLIMP3, Sqbx-G, Win 2000 Pro, Wireless, ~ 5000 MP3 Songs

I have about the same amount of songs. I use a 800Mhz Via C3 for serving
with 768MB of ram. I do also notice the CPU curn on rescan or song
search. I can pretty much alleviate the rescan problems by fiddling with
the Server Settings :: Performance :: Build Items Per Pass. I set it to
5-10 and the server is much more responsive, no music dropouts, etc
while rescanning. The CPU utilization is 100% though, which is desired,
as any lower would mean it takes unneccessarily longer...

I think that the old value of 100 is probably too high. 10 worked
better for you?

Anybody else tweak this setting? I'd like to change the default to a
better value for folks.

Much better. What I noticed is that I used to not be able to navigate
the web interface from my other local boxen with settings at 100. It
would take several minutes to have a frame appear (I use fishbone). With
settings currently at 5, there is no delay. Navigating with the remote
is much smoother now, it used to sometimes, kinda like hiccup when
scrolling during rescan. No longer happens.

Setting it at 100 or 5 does not seems to make any (percivable)
difference in the total time needed to rescan the library. What supposed
to be the trade off with settings at 5?

Anyway my setup is quite underpowered, but I think it is reasonble to
expect a system like this to serve without problems. It is essentially a
fanless system, to eliminate any type of noise pollution...

I'm well confused - is this setting connected to rescan as well as list
building ? I'd be happy to be able to switch off the rescan - my library
doesn't change often (I'm a boring guy that doesn't download at all, only
ripping the eclectic CD's I buy).
Can you give us a 101 on the Build Items parameter and then I can gauge an
appropriate value for me - I thought it was just the length of lists in the
right hand pane (fishbone for me too!)
