I'll dig if I have time. This is just a report.
I tries UnixBench4.1 on x86_64/2cpu/1socket machine. (memory cgroup is enabled)
Following is comparison with a mmtom based on rc4.

15% down in shell script test. Any idea ? (scheduler ?)

Dunno.  There is a largel number of debugging patches at the tail of

the series so they should be the first thing to eliminate.

But I compare mmtom and mmtom, both includes debug series at the tail of series.

I'll revisit this later.
Thanks,

oh, sorry, I didn't read closely enough.
I'd suggest testing linux-next as a first step.
