Re: [sc-dev] idle scsynth CPU usage
i just did a fresh cvs checkout and build before. on my machine a 12"
powerbook 1.33 ghz, 1.28 gb ram, using internal sound. the scsynth
using between 1.0 and 2.0% cpu, shown by the top, the processor
performance set on automatic, if i change the setting to highest the
scsynth is using about 0.5 % less cpu.
i've read you other thread about the problems with your new
powerbook. i think this problem could be related to your new machine,
and its new architecture or maybe something is broken inside of your
powerbook, a manufacturing defect? i don't hope so, but you should
consider this. i had an experience a few years ago, after a lot
kernel-panics and total freezes, i returned my new dual g4 to apple
and they changed the whole processor board after running 48 hours
hardware-test programs without finding some broken. but then
everything was running fine.
if you know any other owners of the latest powerbook. you could test
running sc on their machine.
you could connected them thru a firewire cable, boot your machine in
firewire target mode and then reboot the other machine on your start

I've been noticing something strange with scsynth (this is after
all the other CPU strangeness that has been happening appears to
have worked itself out). Basically, I noticed in Activity Monitor
and top that simply starting scsynth has it running at 8% of the
CPU with nothing happening. The server window reports 0.2%. This is
on one of the 1.67 GHz PowerBooks. Either way... a recent build on
my old machine (1.5 GHz PB) shows about 1% in Activity Monitor. I
just did a fresh build... I'm wondering if anyone else sees
anything like this in a new build? And if so... is this perhaps a
recent change that has done this? Or is it my machine that is
causing the problem... which based on my experiences over the past
couple days wouldn't surprise me!
