Husk forresten også sync før, så du har færre dirty objects.
Et eksempel, hvor jeg sletter ca. 2GB fra hukommelsen.
Kig på cached tallet,

sslug@sslug:~# free | head -2
             total       used       free     shared    buffers     cached
Mem:       4057788    4020616      37172          0     394020    2110732

sslug@sslug:~# sync ; echo 3 > /proc/sys/vm/drop_caches

sslug@sslug:~# free | head -2

             total       used       free     shared    buffers     cached
