Try writing a small python script (or C program) to mmap a large chunk
of memory, with MAP_LOCKED, this will keep it in RAM and avoid that
RAM from being used for caching.
The script should touch the memory at least once to avoid overcommit
from getting smart on you.
I think only root can lock memory, so that small program would have to
run as root.
