If a process tries to allocate and use more than the really free amount, some cache will be dropped automatically. From a performance point of view, this could of course be undesirable, but normally there's no need to think about it. <Why don't we have a command to drop some cache ? or maybe some <kernel rules to do it ? we could gain some more scalability doing that kind of <stuff during low load.Another problem is end-user point of view : < -What's available on a box before swapping ? < -Do I have to add RAM right now ? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
