Here they are (centos6 container on HW node)

pagemap-2M aligned

dump: {
	freezing_time: 1088
	frozen_time: 134642
	memdump_time: 24953
	memwrite_time: 14760
	pages_scanned: 247080
	pages_skipped_parent: 0
	pages_written: 2926
	irmap_resolve: 0
}

pagemap-2M fixed

dump: {
	freezing_time: 1790
	frozen_time: 136145
	memdump_time: 22975
	memwrite_time: 14228
	pages_scanned: 246987
	pages_skipped_parent: 0
	pages_written: 2840
	irmap_resolve: 0
}

no cache

dump: {
	freezing_time: 1313
	frozen_time: 126785
	memdump_time: 20768
	memwrite_time: 13029
	pages_scanned: 247107
	pages_skipped_parent: 0
	pages_written: 2961
	irmap_resolve: 0
}
