Still waiting for swap prefetch
To avoid the manual step (either good morning or good night), I run this in a cron job every hour all day. It doesn't matter that the interactive programs get paged in uselessly several times during the night; even if done right in the middle of updatedb, they just get paged right out again and the cost is insignificant.
I also send messages through some response-time-critical daemons regularly, to "loosen them up." I.e. page in executables, anonymous pages, etc.
