I'm not talking about the scanning speed. What I'm seeing is that vi continuously touches it pages, but as soon as _some_ pages are needed, _all_ pages are swapped out. An operation that took a few minutes before, takes now several hours (hmm, maybe days... the test that I started on 2.2 yesterday still isn't finished :( ). bye, Roman -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
