Sorry for incorrect usage of '~'. I want use the '~60%' to express
performance increased 'about' 60%, not '-60%'. This usage is unusual in
English.

I find almost in one time my kbuilding.
size 384, was alloced in fastpath about 2900k times
size 176, was alloced in fastpath about 1900k times
size 192, was alloced in fastpath about 500k times
anon_vma, was alloced in fastpath about 560k times
size 72, was alloced in fastpath about 600k times
size 512, 256, 128, was alloced in fastpath about more than 100k for
each of them.
I may give you objects size involved in my netperf testing later.
and which test case do you prefer to? If I have, I may collection data
on them.
