Well that CPU isn't the latest >either (10 Years or so) > 18 hours?! On my current home-server which is an Intel Atom D525 1.8ghz it only takes 5 hours. And these are not known for being fast at all. In 1996 ish I was doing it on something like a pentium 75 and I think it still took about 5 hours. So you're right there! 18 hours seems way too long though. These days it compiles things like clang which take a very long time. -- Matt
