i'm pretty sure you refer to this issue: http://drupal.org/node/83738

on the same topic, the main node_load() query takes on average 18ms on 
groups site which seems too high given that groups isn't all that big a site 
yet. this is a *very* frequent query. the SQL is:

SELECT n.nid, n.vid, n.type, n.status, n.created, n.changed, n.comment, 
n.promote, n.sticky, r.timestamp AS revision_timestamp, r.title, r.body, 
r.teaser, r.log, r.format, u.uid, u.name, u.picture, u.data

FROM node n INNER JOIN users u ON u.uid = n.uid INNER JOIN node_revisions r 
ON r.vid = n.vid

WHERE n.nid = <nid>

running EXPLAIN on it suggests that the JOIN with node_revisions is not 
optimized. Perhaps someone else can look at EXPLAIN for this and suggest a fix?
