Hello List
When I roast some CD with 'xcdroast' (or any other application), I can also do it another thinks in the computer. But if I call to the command 'cdrecor' (also I did it with the same options like xcdroast) in the command line the 'cdrecord' take almost the recourses of the computer. Is any way to call to 'cdrecord' and do it another think in the computer in the same time???
I think what you want to look into is the 'nice' command, which allows you to lower an application's priority.
I don't think so. cdrecord uses the real time scheduling class. A process belonging to this class gets as much cpu time, as it demands. This is cdrecords strategy to avoid buffer underruns.
Maybe you can turn this feature off somehow. What you can do is run cdrecord with less privileges. Only root is allowed to put processes into the real time scheduling class. -alf
I think this is a red herring. Though only burning at 12x, cdrecord takes up less than 1% of the cpu on my system so unless OP's burner is two orders of magnitude faster...[though even then I have a feeling it still wouldn't use appreciable cpu].
OP: are you really just doing 'cdrecord dev=0,0,0 some.iso' or are you trying to do something like 'mkisofs ... | cdrecord dev=0,0,0'. mkisofs does use a significant amount of cpu[though it still doesn't peg my system], and you may have better results by making an iso image in a seperate step. This also has the added benefit of allowing you to mount the iso before you burn it to double check that it is correct.
I'm using :
cdrecord dev="0,0,0" fs=4096k driveropts=burnproof -v -useinfo speed=32 -dao -eject -pad -data "file.iso"
I will try give less speed , Thank you for the idea.
