Re: [sc-dev] idle scsynth CPU usage

hi josh,
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 volume.

Hi everyone,

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!
