Hi you all guys!

I've decided to try to configure & compile a kernel on my own. This is the first time I do that, and I'm following a pretty recent guide:
http://www.linux.org/threads/%EF%BB%...oduction.4203/

I'm at a point where I'm being asked to select the SLAB allocator. I had absolutely no idea about what it is, so I have surfed the web a bit, and got an idea about that.

Now I have the 2 options(I'm configuring kernel v3.11.6) SLAB or SLUB -even if the guide tells me I am supposed to be displayed 3 options -SLAB, SLUB and SLOB-, but i think SLOB has been removed in v3.11.6(in the guide he's compiling v3.9.4).

Anyway, the only thing I've found so far is that SLUB is more recent and apparently became the default allocator from v2.6.23, even if it looks the default for me is SLAB.

Well, my question is: what is the best, why and what are the differences?

Cheers from Italy guys,

Marco

From a quick read, slub is slab with shorter queues, and therefore is preferable.
I gather slub is not 100% so slab is the backup.
