Without even citing others' answers, simply forget 32 bit. It's the
past, let them rest in peace.
Firefox/Mozilla/Seamonkey, "because there is no demand". You also have
to run similar tweaks to get other media formats running on 64bit. There
is a wrapper for running 32 bit plugin-ins for a 64bit firefox, but
nothing of that is nice.
It's a non-issue, the solution is to use the 32 bit version of Firefox
which runs fine on 64 bit Linux. I'm using 64 bit Fedora with the 32 bit
version of Firefox, the Java plugin works fine.
All correct, but it means a lot of code duplication, too. A 32-bit
firefox also requires 32-bit libraries, all I *also* need to keep on the
system, for a second time. Funny enough, the java VM is available in
64bit, only the plugin is not. I wonder what's so hard providing it.
The speed advantage of 64 bit over 32 bit is questionable - I don't see
any major advantage unless someone really provides me with objective
timing measurements. Yes, I am using a 64bit system running a 64bit
Debian here. But for a different reason - my software has to be 64bit
compatible, and it's best tested on a 64bit system. For my programs, the
performance advantage of x86_64 is only marginal. For servers, the
larger address space is, however, a significant advantage.
I've been running 32-bit on this machine for several months. I played
with 64-bit. Like you, I didn't see much of a gain. Sure there was
some. But not a lot.
I ran into problems with 64-bit. I had one particular one using
openSUSE, Mepis, Ubuntu, CentOS and several others. IOW it wasn't
limited to a particular relase or distribution. When I wanted to log
out, I couldn't. I could tell the desktop to log out over and over and
over, but it never did. If I hit Ctrl-Alt-Backspace I'd find myself at
the BIOS screen a couple of seconds later, whether I previously tried
to logout before forcing X to quit or not. I haven't had the same
problem with 32-bit.
That was the main problem. But I also ran into problems finding codecs
and plugins that were 64-bit. Yeah, I could do the 32-bit while running
64 game, but what's the point in that?
Add those things to the X/logout problem, plus the fact that I didn't
see that much gain, and that was enough to send me back to 32-bit.
Others might want to sacrifice functionality, convenience or other
things based on one prinicple or another. But I'm not willing to do it
just for minor gains. I might if the differences are large enough.
All that said, I haven't so much as run up a 64-bit live CD in the last
6 months. Maybe I'll try it again soon to see if things have changed in
