Description Konrad Rzeszutek 2006-06-15 12:16:06 EDT
Description of problem:

Make CONFIG_NUMA part of the i386 build.
Comment 1 Konrad Rzeszutek 2006-07-21 10:51:44 EDT
One config option needs to be set to take advantage of this:


Also for this to work on the IBM x460 two patches need to be applied (both being
pushed upstream right now).

Comment 2 Konrad Rzeszutek 2006-07-21 10:54:08 EDT
The two patches are in BZ 184806.
Comment 3 Konrad Rzeszutek 2006-08-14 12:53:38 EDT
The disadvantages (1% performance loss, no ISV requirements, no market for this)
are more numerous than the advantages (1-15% performance benefit for selective
IBM hardware, NUMA exists in 64-bit and customers need 64-bit to take advantage
of more memory), therefore setting bug as WONTFIX.
