I'm getting ready for Gutsy's release, and was thinking about going to
the AMD64 version, but wasn't sure of what the current issues around
64 bit were. As I remember last fall I chose i386 as many users
reported issues with 64 bit versions of 3rd party software - OO
printing, Flash etc., however, a year has gone by and I assume some of
those problems have been eliminated.
A search through Ubuntuforums brings up a discussion on the subject,
however the newest entry is from 2005. A google search for "AMD64 vs
i386" + Ubuntu did bring up an interesting comparison test
http://fedora.thelinuxpimp.com/files/amd64vsi386.pdf
comparing the LiveCD versions of Dapper and Edgy and says:
Following conclusions were made:
1. It was clearly shown that most of applications have better
performance in 64 bit environment.
2. Performance degradation was observed in very few cases and it was
very low – in about few
percents – lame MP3 encoder, GNU compiler.
3. Most of applications have 20-30% performance gain in 64 bit mode.
4. In very few cases the gain was extremely high – 70-100% –
mathematical processing in octave, image processing with ImageMagic.
Which, if true, seems reason enough to switch.
How do list members who have tried both versions lately see it,
especially any of you who have already downloaded the beta of Gutsy?
I am using 64 bit of debian (lenny aka Testing) since mid-July. Before
that I used 32-bit debian etch/testing, ubuntu etc. and I must say,
1. Almost all applications have faster GUI responsiveness.
2. Few applications start/stop faster than 32-bit counterpart.
3. Encoding mp3 is really better. (I didn't do any video encoding
though)
4. I am not into scientific/mathemetical field, so can't comment about
that.
5. 64 bit Gnash plugin is working with many websites. Though I didn't
get youtube (32bit flash must be installed)
6. 64 bit Java is just ok.
And I don't know if this related to 64-nit or not, I found 64-bit
application crashes less, even in debian-testing version. Though I'm
using debian, but still I think ubuntu will behave in same way. :)
