Hi Mauricio,

The tests in [5][6] and [7] have been done with a 44GB memory VM.
This VM usually has 64GB of allocated memory.
The goal was to verify that the load of the whole btree in RAM was not prevented (like in mca-reap -> down_write_trylock).

All this kernel stuff is rather new to me, so I may be following a wrong lead.
