Some statistics here:
https://www.open-mesh.org/projects/batman-adv/wiki/Kmalloc-kmem-cache-tests
In a nutshell, on a small TP-Link TL-841NDv8 wireless router
(MIPS/AR9341), I was able to achieve 34% more global TT entries
(or 25% less RAM usage).
Regarding SLAB_HWCACHE_ALIGN, it did not seem to make much of a
difference. There is a slight tendency for less RAM usage without
this flag. But it is so small, that it might be a coincident, too.
And it is definitely negligable. At least for this architecture.
Regards, Linus
PS: I might make some more, pretty graphs for the other test
variables, too. But for now, there is just this one raw table for
that.
