    Actually, now looks like you have significantly more idle time, so perhaps
    the cross-cpu (or cross-node) balancing isn't agressive enough:

          4583 10.0% default_idle
          2246 1.4% total
           377 12.0% zap_pte_range
           210 15.2% free_hot_cold_page
           161 9.3% buffered_rmqueue
           138 47.4% __set_page_dirty_buffers
           102 0.7% do_anonymous_page
            54 4.9% clear_page_tables
    ...
           -51 -4.3% file_move
           -63 -7.9% pte_alloc_one
           -63 -3.4% path_lookup
           -69 -18.5% .text.lock.file_table
           -70 -8.2% strnlen_user
           -76 -1.0% __d_lookup
           -96 -1.5% page_add_rmap
          -104 -16.8% copy_process
          -109 -2.9% find_get_page
          -118 -28.2% release_task
          -267 -18.8% schedule
          -357 -6.7% __copy_to_user_ll
          -531 -15.2% __copy_from_user_ll
