Now, what do these findings mean for end users anyway. Let's say I have a T5650 core2duo notebook with 1-2GB of RAM. Would my programs start and perform faster, would boot times decrease, would the notebook run cooler and battery time increase? Anything else?
I've tested a 64 bit Ubuntu 9.04 last year, and the only advantage was a barely noticeable performance boots. On the other hand, I had to deal with nspluginwrapper, ia32 and other such nonsense, that made my computing experience worse.
I honestly don't care about 10,000 apache requests per second, so give me a 'real' reason to consider 64bit.
