Slub versus slab

[Andrea Gasparini <gaspa@xxxxxxxxxxx>]

Hi, 
there's someone with experience on Slub/slab performance?
I would understand when to use the first, when the latter...

I found that on numa architecture is surely bettere SLUB.[1]
But this is a rare case, imho. [or: in my experience]

In a "normal" i386 architecture, with some ram intensive applications (we 
did video processing), what kernel should I use? 

Another issue, is how to use the slub options [2], if there's some test 
case, or someone that knows when to use them.

Thanks, bye!
