Furthermore, the reduced allocations seem to produce good effects for

Can you explain why the dirty slots were improved?
I cannot do exactly, but vmalloc() might affect the following
allocations?
Oh, this might be the effect of tlb flush or something?
- I'm not so confident about mm, but vmalloc(),vfree() does this kind
of thing?
Yes, vmalloc() does tlb flushes, perhaps that's the cause.
