My previous build was the newest kde-4.4.4 on the 980x without using -j on the emerge. Yesterday afternoon I tried emerge -j5 -DuN @world on an i5-661 machine I also built for my dad. That emerge also included the newest kde and total was close to 350 ebuild. It completed in maybe 2-2.5 hours which is good. IIRC when I first built KDE on that machine it took maybe 4 hours? Not sure. Anyway, the emerge -j helped, but on the downside emerge died twice in the process complaining about something. If I restarted emerge it didn't fail the second time and continued on until it died again, and I had to restart it again. I think I read here about others having that problem. Nothing was bad in the end, and everything got done, but it took a little more hand holding. Thanks for the pointer. Cheers, Mark
