The most promising tunable that shows consistent reduction in slab memory
is slub_max_order. Here is a table that shows the number of slabs that
end up with different orders and the total slab consumption at boot

Hi,
On POWER systems, where 64K PAGE_SIZE is default, I see that slub
consumes higher amount of memory compared to any 4K page-size system.
While slub is obviously going to consume more memory on 64K page-size
systems compared to 4K as slabs are allocated in page-size granularity,
