Thanks, Chris! Even so, KSM seems not to be working: root@ubuntu:~# cat /sys/kernel/mm/ksm/max_kernel_pages 253738 root@ubuntu:~# cat /sys/kernel/mm/ksm/run 1 root@ubuntu:~# cat /sys/kernel/mm/ksm/pages_sharing 0 root@ubuntu:~# cat /sys/kernel/mm/ksm/pages_shared 0 Is it possible that, as I've mentioned in another message of this thread, the version of glibc of Ubuntu Hardy Heron doesn't have support for KSM?
