Hi! Reading /usr/src/linux/Documentation/filesystems/proc.txt leaves some questions open. For example some values are break-downs of others. I'd like to see documentation on how these relate. For example (3.0.101): MemTotal: 132156332 kB MemFree: 22448480 kB Buffers: 1484072 kB Cached: 81252832 kB SwapCached: 0 kB Active: 24216920 kB Inactive: 65789500 kB Active(anon): 20268724 kB Inactive(anon): 4617808 kB Active(file): 3948196 kB Inactive(file): 61171692 kB Unevictable: 48840 kB Mlocked: 30444 kB SwapTotal: 20964788 kB SwapFree: 20964788 kB Dirty: 496 kB Writeback: 0 kB AnonPages: 7317972 kB Mapped: 15927688 kB Shmem: 17602008 kB Slab: 1162160 kB SReclaimable: 907496 kB SUnreclaim: 254664 kB KernelStack: 8864 kB PageTables: 1361780 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 79158152 kB Committed_AS: 66056192 kB VmallocTotal: 34359738367 kB VmallocUsed: 305164 kB VmallocChunk: 34292267888 kB HardwareCorrupted: 0 kB AnonHugePages: 4997120 kB HugePages_Total: 7700 HugePages_Free: 62 HugePages_Rsvd: 44 HugePages_Surp: 0 Hugepagesize: 2048 kB DirectMap4k: 301296 kB DirectMap2M: 19611648 kB DirectMap1G: 114294784 kB Which numbers sum up to MemTotal? It seems Active(anon) + Active(file) == Active (and similar for inactive). What is the relation between Unevictable and Mlocked? Is "Unevictable >= Mlocked" all the time? It would give some insight how things work if you document the relations between some of these numbers. (I'm hunting for a condition for very bad disk response times, suspecting some memory pressure. I suspect too many dirty pages for some reason...) Regards, Ulrich -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
