These plans seem identical (though the fact that the leading whitespace
was trimmed means it's untrustworthy -- please in the future send them
as text attachments instead so that your mailer doesn't interfere with
formatting).  The 8.4 plan is even a full second faster, according to
the "total runtime" line.

The slowness could've been caused by caching effects ...
