The RSS bounds are *DYNAMIC*. If there is contention for memory --- if lots of other processes want the memory that that emacs is holding --- then absolutely you want to cut back on the emacs RSS. If there is no competition, and emacs is the only active process, then there is no need to prune its RSS. --Stephen -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
