final sign on the "road to 64-bit"

I wrote about switching to 64-bit Ubuntu a few days ago.

Then I added an update a few days later with more information.

The major conclusion there was that if you have > 3GB RAM, unless you are using a customized kernel or the 64-bit Ubuntu, you are not going to be able to use more than 3GB RAM.

Anyways, not that I needed more convincing, but tuxradar has a damn good write-up with performance numbers comparing Ubuntu 9.04 with 32-bit and 64-bit version:

Ubuntu 9.04 32-bit v/s 64-bit performance numbers

I think this conclusion summarizes it nicely -
"Putting aside the issue of Flash for a moment, moving from 32-bit to 64-bit is pretty much painless. In fact, you can't tell the difference without running uname -a in a terminal - all the programs you're used to are likely to run identically, and ultimately it's only a matter of time before x86-64 becomes the standard."

There is no turning back, I am convinced 64-bit is the way to go.
