View Full Version : Softsqueeze, linux and pauses

I doubt the problem is Linux related. You might have another process that
is hogging up the system. Even when I was running my slimserver on a 300mhz
Celeron cpu with 256MB of RAM it never hiccuped or paused in any way, and
this was with running a squeezebox, slimp3 player, samba server which was
the master PDC for my windows domain and several other processes.

Subject: [slim] Softsqueeze, linux and pauses


Hi

My 'java' process uses 30mb of resident memory and 263mb of virtual memory.
It however never uses any cpu according to 'top', however when I play a file
(and there is a pause which occurs about 25% of the time) idle cpu % goes
down to 0% for a few seconds without any obvious process taking up the
resources.

Just tried using softsqueeze 0.6 on the linux machine connecting to a
windows macine runnign an old slimserver version and a similar thing occurs.
So I dont think it is a resource issue with running softsqueeze on the same
computer as slimserver.

I have also tried connecting to the linux slimserver froma windwos xp
machine running softsqueeze 1.3 and none of these problems occur. So it
appears to be a linux only problem.

Very odd!
