Fair enough, whilst I think the link (if it is by Linus) is over the top
I assume he must have good reason for being so flagrant.

I assume the main point is install 64-bit, some have said 64-bit is
slower in some respects but I expect that's marginal and will be glad
when everything runs perfectly on 64-bit.

I will say I have 4 OS running on a PAE kernel right now using >3Gig of
mem and it's running well but I did also disable PAE along with various
other things on one system that was struggling with performance.

Seems 12.04 may have moved to PAE by default but I'm not sure of that?
