Hi ceph-devel, Did anyone ever consider using madvise MADV_MERGEABLE to enable kernel samepage merging for the ceph-osd? Typically this is used on kvm hosts to dedupe the VM memories, but naively I was thinking that since our osdmaps are duplicated (a few 100MB per daemon) we might profit as well. Though, perhaps these maps are changing often enough that KSM wouldn't help... no idea. Any thoughts here? -- Dan CERN IT -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
