Hi, Is there a portage option that will limit the number of cores used by emerge? For instance, in a chroot on a 12 core machine I want to limit emerge to not using more than 3 cores?
If possible, I'd also like to limit the total disk bandwidth consumption during emerge. For instance, when untarring a big file to do the emerge at times the disk consumption gets to high and the machine becomes laggy. Is there an option that addresses this? These questions are mostly about being able to update a chroot mid-day without other tasks slowing down too much. I don't care how long the chroot really takes to get a huge emerge done, but rathe just keeping the machine very responsive while it's happening. I already use: MAKEOPTS="-j3" PORTAGE_NICENESS="15" which helps (I think) but it doesn't totally address either of the issues above. Thanks, Mark
