If I understand you right, your scheme has the fundamental flaw that one dcache entry on a page can keep an entire page full of "slackers" in memory, and since there is little correlation in usage between dcache entries that happen to get stored on a page, the result is that the effectiveness

[reiserfs-list] Note describing poor dcache utilization under high memory pressure

2002-01-28 Thread Josh MacDonald
When memory pressure becomes high, the Linux kswapd begins calling shrink_caches() from try_to_free_pages() with an integer priority from 6 (the default, lowest priority) to 1 (high priority). Looking specifically at the dcache, this results in a calls to shrink_dcache_memory() that attempt to fr
