1) Linux doesn't track shared pages (which is not the same as shared
memory) anymore--the field the in 'free' output is just there to
avoid breaking software. Use the 'ipcs' command to list shared
memory segments--you'll find Postgres is using what you told it to
(otherwise it woudn't start up at all).
2) The -performance list is a good place to find out why queries are
running slowly.
