Partner organization:

openSUSE currently builds i586 binaries with a couple exceptions.  As
it currently stands openSUSE 11.1 permits a Pentium 1 but requires at
least 256MB of RAM with 512MB recommended [1].  The likelihood of a
person having a system with an original Pentium and 256MB (esp. 512MB)
of RAM is quite low.   Since the i686 architecture was introduced in
1995...2010 or 2011 is a suitable time to migrate the x86_32 target
architecture without adversely affecting the majority of users.    The
Fedora Project is making this same transition for Fedora 12 [2]. Any
growing pains they experience can be used as guidance for the
transition in openSUSE 11.3 or 12.0.   [1]   [2]

Business case (Partner benefit): By moving to i686, openSUSE should receive a slight
performance increase while maintaining support for an incredibly broad
range of x86 chips. Any boost is helpful on systems with less
processing power, such as netbooks/nettops or older systems (Pentium 2,
original Athlon etc.). Moving to i686 is a way to boost performance the
performance of openSUSE at the margins without having to delve into
experimental or otherwise under-tested methods.

What does i686 bring? Just the CMOV instructions. That alone does not
convince me, and binaries are already at least compiled with -

Hi, I have read and heard much criticism from people with different
expertise on computing and many say suse / opensuse is heavy and slow.
For example it is one of the disadvantages of Distrowatch (Top Ten
Distributions, advantages and disadvantages perhaps you can
improve system performance by optimizing the most modern hardware and
current ( common, frequently found in the home and office). If there
are surveys that can observe the number of users who have older
computers would be good to go up the link. Greetings.
