Hi, I took a look at the allocator wiki,
My previous experience with Vmware gave me the impression
that profiling of functions' call time in it is sometimes unstable.
Do you want a new profiling result based on real hardware?

The comments in this thread seemed to suggest
the direct comparison with kmalloc,
while the current wiki benchmark is based on user space.
If you already have the test suit for kernel,
I wanna have a try in my environment.
