Are you referring to raising the per cpu array limit? I don't think you tune that using /proc/slabinfo. However that does not solve the problem, it only delays it. It needs to grow/shrink dynamically based on need. I am not only referring to frequently draining of free objects but also as a result of this refilling the object array due to subsequent allocations and so on.
