Erik,

Wow, thanks for the post.

We've just started testing the option of sizing shared_buffers bigger than 
the database, and using forcedirectio in benchmarks at Sun.  So far, our 
experience has been *equal* performance in that configuration, so it's 
*very* interesting to see you're getting a gain.
