Fedora desktop. One of the problems with that is that you need a
reproducable representative benchmark typically scripting all the mouse
clicks and keypresses, using identical data sets and so on. They are hard
to produce and I'm not aware of any Linux ones that don't involve payment
of large sums of money to third party who runs their own closed secret
test and produces a number you can stick up in lights. So let me turn the
question around - given that the evidence from microbenchmarks and CPU
architects is that 64bit is the better choice can you show any
good quality benchmarks showing it isn't a win ?
I agree getting formal, almost perfectly fair benchmarks is infeasible.
But I haven't seen any informal benchmarks that come close to showing a
significant performance gain. I've already pointed to such an informal
benchmark showing negligible difference.
However if you cared about performance you wouldn't be running
Gnome or
Kde ;)
I don't particularly care about small differences in performance, and I
do like running a highly featured desktop. But the real question is
whether any performance advantage of desktop 64-bit for < 4 GB is worth
the hassle. As to that, I'm still very unconvinced.
