Just a follow-up. |

I got rid of llvm on my Gentoo nvidia machine and so far see no ill |
43 |
effects. Granted, I'm using an i7 980 Extreme, 24GB with an nvidia |
44 |
960-based card, so it's pretty good hardware but I've seen no ill effects |
45 |
so far. |

Additionally, with Google releasing Google Earth as a web app at least |
48 |
inside of Chrome it runs fine. Pan/zoom/tilt 3D views of the world. Lots of |
49 |
fun and if it was faster with llvm I don't think I'd notice it. |

As for my wife's laptop which started this discussion I had an emerge 2 |
52 |
weeks ago of about 200 packages, mostly KDE, which took almost 24 hours to |
53 |
build on a 5-6 year old laptop.This time around I have about 175 packages |
54 |
today. We'll see how long it takes as a data point but I've decided to move |
55 |
her to Ubuntu. I think I need to be spending my time more productively than |
56 |
building this much code this often. I already run Ubuntu as a VM on my |
57 |
Gentoo machine due to apps not supported (or not building correctly) by |
58 |
Gentoo in portage. Sad as it will be the first non-Gentoo boot in my house |
59 |
in about 15 years. |
